I used to belong to the Minnesota Trailriders. It is not a "Jeep Club" per se (although 95+% of the 40 or so rigs were Jeeps) so they don't exclude non-Jeeps (in fact they do exclude fulls-size muddin' rigs). I got a few bemused reactions from some of the guys when I joined with my Trooper, but no negative comments really, just curiosity. And after I wheeled with them a few times, all was good...that's usually all it takes.
