festivals, flea markets, and surplus dealers

I'm rather new to the mailing list, and I poked through some of the previous messages on the site, but didnt see this one directly answered. I live in texas, and know of a few here haaug meet, first saturday, san antonio's 2nd sat, but is there a place where I can find out more of them located in this area (texas, oklahoma, arkansas, lousiana)? I figure here would be the best place to ask, because I'm really not interested in buying pc stuff, but love old unix equipment, and misc electronics. Any huge festivals that I should be going too every year that I'm not? (I go to trenton nj)... what about surplus places (I love to find junk at places that take computers to scrap them for metal... I get some awesome deals there)? Any help would be nice :) Thanks, jon
