You know I've wondered if that ever happened around here. I'm still a little noob to the forum but I'd at least make the attempt at showing (between work, wife, kids, you know the drill). It would be interesting to just stare under each others hoods and compare notes. Not to mention the networking aspect. I never fail to find some useful link between the guy I just met and something that pops up two months down the road.
Location? I dunno. I suspect most are in the OMA/LNK area. Either of them works. Though it'd probably be more fun to make a fishing trip out of it in the Sandhills. (Or duck hunting!!!)
