I think your best bet for "local" photos would be keeping a close eye on the local bloggers or by searching this website

There are several apartments/condominiums in Friday Harbor all within walking distance of downtown. Of course everyone's idea of walking distance is a little bit different.
We have a couple supermarkets; one is located two or three blocks uptown... it is cheaper and bigger and favored by most locals. King's market is downtown right on Spring Street. Website:http://www.kings-market.com/market.html
I hope that helps a little bit... thank you for using the message board.
