No reason not to consider multiple TS's around the country. The CA boys could probably have one of their own, there are enough of them. NM-UT-AZ-CO probably isn't quite enough folks, unless the meet was near the Front Range, then it could draw KS, OK, WY, West TX, etc. Pac NW ?
If there were only going to be one, with max participation and max number of old trucks driven there, I'd guess it should be in northern MO. It all depends on what the criteria is, the place, etc.
I would be willing to do it again, and I also would be just as willing to travel someplace else and enjoy a change of scenery. The regional idea is a good one. I'll just go with the flow on that. There are indeed things that I would do differently next year. But I'm gonna say this again--that entire week and weekend with total "strangers" was seemingly perfect. I think Larry summed it up while we were talking about it--like minded people with similar values and ideas..... I've honestly had family cookouts and reunions that were 20X more stressful.
