2013  I thnk. Googled, found GATR.  What caught my attention was "any 4x4 vehicle, not just Jeeps" I was new to wheelin and wanted a place that me and my truck would be welcome.  Found it!
  My first ride was the first annual cook out Trey mountain ride.  Ha, I put it in 4 low for the whole ride!  Now I do most of it in 2 wheel.
  I think for new members it should be required to read about "tread lightly" even before joining as a guest.  People just don't know, I was one of them.  Awesome club, awesome members, awesome info.
