I dunno if I would come to this, but you guys should do what dumbrella was talking about before it died and do like, a "cabin in the woods con." Like, find somewhere that you could rent either camping or a cabin or something, preferably near a lake, and then just like hang out and drink and swim and fish and all that shit. That sounds like badass awesome to me, personally.
Alternatively, DenverCon, for a good music scene and a beautiful setting in a place not too totally expensive, plus all sorts of fun outdoorsy shit like hiking and climbing and again, lakes.
Nashvillecon, because fuccin hell Nashville is an awesome city if you go to the right parts of it, and also really cheap.
Otherwise, San Francisco and Austin are the two best choices. Portland isn't that much fun to Con-steeze in(did it with dumbrella,) and the rest are honestly pretty played out.
