As a book store employee where 1/4 of the people in my store play DFRPG and half play other RPGs (Hell, only two people there don't read Dresden), I recommend checking out gaming stores first but you also might check out a local Borders or Barnes and Noble. I mean, you could at least see about putting up a flyer for trying to build a gaming group or something. Being allowed to put up flyers is pretty case by case as far as whether a store will allow it but it never hurts to ask. Just mention that to play the DFRPG you're supposed to read up through Small Favor at least so it would also promote their store in that regard. Besides, if you're lucky you'll happen to talk to an employee who's trying to put together a game or wants in on a game.
