East Sheen is a fairly well-to-do suburb of London. Mostly home to London workers who've got plenty of cash and full of yummy-mummy types doing the school run in 4X4s dressed in sports gear ready to go for a run/yoga/gym and then meet for a coffee with other mums in one of the area's many coffee shops or nice pubs. House prices are extortionate - East Sheen shopping area is mainly estate agents, nice coffee shops, boutique clothes and homewares plus a few 'high street' chains, banks and middle-class supermarket "waitrose'. Oh and Sheen Sports - which I think is where RY worked after quitting his full time job. Also Up and Running shop - big supporters of RY.
Richmond Park and the Thames towpath are half a mile away, so on a weekend it looks like everyone from the surrounding area descends to run/cycle/walk etc.
Generally it's a pretty quiet place where not much happenshttp://www.eastsheenvillage.co.uk/history/
I do NOT know Dustin Brooks or any of the other people that have been mentioned on this thread. As I don't have kids (seemingly unlike 90% of the other residents of East Sheen), I probably don't mix in the same circles as RY and Co, you know schools and stuff, where the 'kids' are!
