Was this at that off-road clinic that guy out of Houston puts on?
Yes (offroading101.com). I did the 2nd-level clinic this time. The first two levels of classes are at their ranch just outside College Station (pictured above), it's quite beautiful there. The 301 class they do at Hidden Falls (all day, and you can stay for night trail runs if you want). They've been toying with the idea of Colorado trips, too.
