You'll get sooo much stick about Bracknell but the truth is that it's actually an amazing place to live. I've lived in Portsmouth, West London, Bath, Dorset, Cardiff, Chichester and a couple of other places but in terms of "easy life", value for money housing and lifestyle I'd say that Bracknell has been my favourite place so far.
There's a proper community vibe in the various estates, and you can walk nearly anywhere without crossing a road. If you're coming into town from met office direction the underpass by the Manor is absolutely fine you don't need to avoid it- there's always a lot of people there as it's right next to the college. If you're coming from priestwood direction then you can walk through Arlington square and go in past the point/up through McDonalds.
I have to admit that around Bracknell my guard is often way, way lower than it is in other places. The "low level nastiness" you get in big anonymous towns just isn't there. Yes some of the kids are dicks, but generally everyone is just... Nice. It's becoming more multicultural too which is lovely, it was a bit of a gammon stronghold for a while.
If you've got a family check out the red and yellow routes around town. They're traffic free routes that take you through the town centre and past all the way from Jocks Lane at one end to Swinley forest (my end of town... I did live in Binfield road for a bit but I prefer it over this side because the forest is amazing, you can walk for hours!!) at the other. There's something like 25 playgrounds on the route.
The design of the estates is pretty cool- lots of the residential roads are non-through routes which cuts down on traffic/speeding near houses. A lot of them are alphabetised so you can find your bearings (for eg. all the A roads are next to each other- Appledore, Aysgarth, Ashbourne so it's dead easy to navigate). You also find that quite often the foot and road networks are independent of each other so you aren't as exposed to pollution while walking around.
Each estate generally has a little shopping precinct with a shop, takeaway or two, a doctor's, and a pub. There's a 3 or 4 children's centres, and they run some lovely groups for <5s, mostly free or nominal fee. The local libraries are an absolute gem in the town too, lots of events, authors and kids stuff going on. If you're on your own then there's a couple of "Social prescribers" which is a council run initiative which points people in the direction of community groups or hobby groups which is nice.
The We Love Bracknell Facebook group is a good place to start to see what's going on (although there's the usual local moaners!) as is People Help the People. There's always some event or other going on.
