yeah free motion, probably good if you just want to be led around, they seem to do some more adventurous stuff the last time I saw them, but the good stuff you wouldn't bring rental people on.
Depends the level your at though.
GC ranges form Fireroads, to flowy singletrack to gnarly verging on suicidal.
I never get to ride the stuff I really want to when I go, because I still want the people I'm with talking to me when I've finished the spin. [Apart from Aiden Mac of course:)]
Gotta do LOTR if your there, [purely to marvel at real trail building] it's the one thing you can't miss, even if you do nothing else.
