You should go to Disneyland!
True dat.
If you're in Santa Ana, you'll be next-door to Garden Grove. You might check out Brookhurst Hobbies (
www.brookhursthobbies.com) - over half the shop is devoted to models (especially model war games) but their RPG selection is quite good and they have gone to GAMA before as exhibitors (I know at one point they were a US distributor for a miniatures line). Depending on what part of Santa Ana you're in, it will be a 15-30 minute drive on surface streets. They're nice and pretty knowledgeable (though a couple employees will talk your ear off if you let 'em).
If you are willing to go a little further afield, there's a shop in Fullerton called Game Castle (about 30 min north of Santa Ana via the 55 Freeway), and one in Long Beach called "The War House" (about 25 min west-northwest of Santa Ana via the 405 Freeway) - google them by name and city to get directions. If you want mainstream games, they're the place to go.
Game Castle tends to have all the newest stuff and is a genuine RPG shop (instead of brookhurst hobbies, which splits its attention), and has a pretty extensive collection of Dragon (and possibly Dungeon) magazines, as well as carrying most of the popular RPG lines (WW, Palladium, GURPS, etc.).
The War House is a step back in time... while they have a lot of the "new stuff" in their front room, they have a back room with boxes and boxes of old stuff - I'm talking Mayfair Games, Flying Buffalo supplements galore, old 1e and 2e stuff, etc. It's a little tricky to get into their parking lot, but for a vintage gamer, I can't think of a better place in the area. The owner and his buddies tend to game in the back room, and they have some REALLY old stuff that "ain't for sale" but is cool to look at.
Hope that helps. Also, if you want anything I happen to have for sale (see my sig) - I live in Garden Grove, and I would be more than happy to sell or trade stuff to ya; you can pick it up or I can drop it off... and you'll get it for much less than MSRP.
