OK and may have to name change. My grandparents farmed near Canterbury and had business interests in Folkestone. My mother lives on the coast, a nice bit and I was brought up there and despite leaving 40 years ago, visit a lot.
Canterbury is not the lovely Cathedral City it once was. The shops aren't great and Fenwicks is good but not a patch on the old Ricemans. It's far less "posh" than it was.
The schools are great if you can get into the grammars. Growing up lots of families sent their 11+ children to the grammars and the ones who didn't pass to private schools. I guess as everyone now does GCSEs the secondary mods have improved but there used to be a real pecking order of what was acceptable.
It can be quite narrow in outlook, certainly in my day there were people in the coastal villages who had never been to Canterbury! There are worrying pockets of bigotry - one only has to look at the rise of Reform. My mum calls locals in her area "Fannit Fickies".
Transport is awful apart from the fast trains and lots of the bus routes have been altered beyond recognition.
Some of the big proposed developments in East Kent have had large numbers of accommodation purchased by South London Councils - go figure!
Parts of it are lovely and I'd venture that Deal, Faversham might be worth a look.
I wasn't aware there were no longer A&E services at Kent & Canterbury. Reputationally local health services have always been poor. However, on a limb here. Mum is 89 and in recent years has had a seriois heart condition and was swiftly referred for a TAVI (so specialist it's done in London). Subsequently she's had therapy for anxiety, good GP care, excellent heart follow up and all the tests under the sun to deal with a collection of symptoms which have diagnosed a meningioma, silent strokes and Parkinsons. I am gobsmacked at the speed and quality of care she has had.
I'd happily retire back to that neck of the woods if I could persuade DH.
At your stage of life @MagicThanks I'm not persuaded there's much for teenagers. In my day it was Pony Club, Young Farmers, YCs and Rotaract. If you weren't in that circle Girls and Boys Brigade or Church or grotty clubs and glue sniffing. I doubt that's much different.
