The Safeway in Strood has a great selection of beer! 
Hoo is kind of far out - but I imagine it's a nice place to live. The school there has a good reputation, from what I know.
Are you thinking of Hoo St. Mary's?
Hoo St. Werburgh is just a 191 bus ride away from Rochester & Chatham & Strood.
Only takes about 20 minutes.
Hoo is an alright place to live...
Its residents are a mix of upper, mid-level, and working class folks.
Kind of strange compared to San Jose where the "levels" are more distilled & distinct.
What I mean is, back in SJ the rich live with the rich, the poor with the poor, but here in Hoo they are all mixed together.
My only complaint about Hoo are the young lads who vandalize phoneboxes and race their cars down our streets doing 60 mph...
If you like curry, you absolutely must try Hoo Spice. It's a take-away on Main Road. I've tried many other curry houses/take-aways but Hoo Spice beats them all. They make a lovely Bombay Aloo.
