Aw maaaan... I really hope one day I actually get to play a (pen-and-paper) game of Shadowrun. I can't believe it's been so long and it's still never happened X-)
Most comic book and games stores have boards where you can search for groups. Craigslist maybe too? It's not such an uncommon hobby and if you find no group to join you could always start your own!
Go for it. It's such fun.
