My LGS is called Cosmic Comics. They're a privately-owned store that's been around as long as I can remember, and I'm 32. They have something for everyone there, and run tourneys every Friday night.

Other than that, if you're in the area, you can find a Lone Star Comics location to play at, but eh, chain shop.
Happy Gaming!!
