TNT was formed because the Frontier and Pathfinder guys felt kind of left out of the SWXC... so there's a lot of membership overlap... but it's not exactly the same group.

It's always been made clear that SWXC invites anyone to come out and join in the fun - but I think some still felt like they were being tolerated rather than being a real part of the club... To me, the clubs are coexisting quite nicely. SWXC has a larger member base, great club discounts, and experienced people. TNT has the excitement and drive (read: activity level) of a new and smallish group.

I like both.
