The Gauntlet moved. It hasn't been on 11th street for ages. They moved on to Prescott by the old Costco building, and then they moved again really recently. I don't know the new address, I think it's on Coffee Rd, somewhere between Sylvan and Rumble. Just call them at (209)526-5591. It is a great place to find gamers and gaming stuff.
I'm not from Modesto, but I just moved away from Manteca, also to San Diego. Funny coincidence.
