So I just wrote a 1600 word review and somehow it didn't go through, so here is the short version...
Had a great trip with our guides Ryker and Keegan. Overall recommend. Slightly sad there weren't more zips, but the excitement factor made up for it.
Details: Drive out. 2 zips, second you can go upside down if desired. Ditch gear, short hike to swimming hole. 3rd zip is the swimming hole (~15-20 minutes) to jump in / zip in as many times as you want. Drive to 4th biiiiig zip. Super fun/thrilling - 4000', speeds 45mph+. Didn't see as many bugs as other reviews suggested - store sells bug spray for $5-8 though.
