Vancouver clubs = op-for, british columbia airsoft club (BCAC), fraser valley airsoft association (or something like that, FVAA). I play predominantly with Op-For. If you're of age (18 or older), you should come out sometime - it's a good way to see people's guns and gear and get an introduction to the game of airsoft. Rules are a little different if you're younger than that, though - but Op-For might be able to accommodate you.
If you can, get age verified. You can do that at most of the local club's games, actually. Speaking of clubs in the Lower Mainland, I'm sure that there might be one or so others that have slipped my mind. Anyway, sign up on those club forums and ask around for a ride. After you've been out once, finding rides to/from games becomes a bit easier.
