Are you medical profession? We have some amazing hospitals here, Addenbrookes, Papworth, etc. I'm in West Cambridgeshire, and Cambridge itself has a Science Park. The clue is in the name, I think.
We also have some excellent schools here, and, yes, some are over subscribed, although I think that tends to be the case wherever you live, sadly. We have excellent countryside walks, literally on the doorstep, and further afield. London (King's Cross) is an hour commute. There is no train to Cambridge, but there is a "guided bus". Peterborough, another city, is about 20 minutes by train.
It's also a lower crime rate area. Your car insurance would go down because of this. Our broadband speed is actually quite good! I know this, because my son told me, and he should know, because that's what he does for a living, the fibre optic thing. It's a slower pace of life, and I love it! My kids have never had a problem with social activities, at all, ever, since we moved here. I have not regretted it for a single moment. We're close to the A1, and the A14 and therefore the A14/M1 link. Not close enough to appreciate the noise though! We have no overhead aircraft, except for the (very) occasional RAF jet. No major road traffic jams, unless there's an accident. We have Tesco, Marks and Spencer, and Waitrose on our doorstep, together with Aldi, et al. We are within driving distance of The Grafton Centre and Queensgate shopping centres. We also have various Farm Shops. There is also numerous tourist attractions available, some of which are completely free. We have National Trust and English Heritage places available to visit, together with those grand gardens to visit. If that's what turns your pages, obviously! It didn't turn mine for sure! I was completely against moving here. Hated the thought of moving so far away, away from family, friends, you know the thing. When it was decided that we were moving, we got an Ordnance Survey map (maps, I should say, of different areas) and laid them out, and circled where the railway stations were, investigated how long he was willing to commute (an hour, at the most) and then re-circled the ones that were an hour away. Then, we investigated the areas where we (he) would like to live, and this was the closest we (he) could come up with. I have never regretted it, ever. Not even once. The people here actually say "Mornin'" to you. I found that weird, in the beginning. Complete strangers, greeting you. Apart from that, they all talk funny!! It's all part of their character. Lovely people. Lovely surroundings. I can hear the dawn chorus, rather than traffic. I can smell clean, fresh air, rather than car fumes. I can see the stars at night, rather than light pollution. I've even seen a satelite passing over! Amazing!
The public transport system has improved, immensely! When I first got here, I could get a bus to the nearest town, and could spend either 10 minutes before the next bus, or, 4 hours, before the next bus, so I did need a car. You WILL still need a car, because it IS so rural. I would not swap back to my old life, ever. It's not for everyone, I understand that. I know children have a large part in any decision making, but honestly OP, hand on my heart, my 3 have not suffered, at all. Our schools are excellent. 2 of mine have gone on to Cambridge University. Well, all 3 did, but 1 dropped out, so don't know if he counts? We also don't have police or traffic warden people. Our part time police station closed about 5 years ago. We have one set of traffic lights, which is a pedestrian crossing. It doesn't get used, because
A. There's not enough traffic and
B. There's not enough people to use it
We DO have yellow lines, but they don't mean anything. It's only when you get into the "real" towns that anyone bothers about that sort of thing. We have cheap parking, all day. I think it was £2.30 the last time I looked (last year, just before the the You Know What) (sorry! been watching Harry Potter!)
If we know the person blocking our car, on a yellow line (double yellow line even) we just go and ask them if they can please move their car. Never an issue. If we don't know whose car it is, ask the person next to you. They'll know, or know someone who does. Within 20 minutes, you'll be able to move your car, and also, have got to know the locals a bit.
When I first got here, I was bloody horrified! Honestly, it was as rural as I could ever hope to be. I was absolutely convinced that they all must have webbed feet. At the very least, they were all related! They all laughed like drains when they heard that! The DH shared that information. Bless him. We have been welcomed with open arms and open hearts. My neighbour went pheasant shooting just before Christmas, one year. He then arrived on my doorstep, with a brace of pheasant, looking particularly pleased with himself, and I sent him away. "THAT is NOT coming into my house, unless it looks like it came from Tesco!" And off he went! A couple of hours later, he was back, with a couple of (dressed??) sorted out pheasants. Another friend, caught some trout, again, landed on my doorstep, holding these poor fish by the gills, and he was told the same thing. He wasn't impressed, it had taken him ALL day to catch those. Poor thing. STILL not coming into my house looking like that. Did you know, that there is only breast meat on a pheasant? No legs, wings, thighs, etc?
And Trout tastes like mud?
Sorry OP! This has been a long ramble. I just really wanted you to have an idea of what it's like, in real life, to live here, in carrot crunching country. There is miles of dog walking opportunities available also. Rivers (not Thames, obviously) available, for dogs to chase sticks into. All of that stuff. We're actually quite civilised. Mostly!
Happy House Hunting!! xx
