My wife and I were on a cross-country road trip, spending a few nights in Denver. We made a spur-of-the-moment decision to go white water rafting (my first time), and found Performance Tours online. It was one of the last few days of the season, so we ended up getting a raft and guide, Kurt, all to ourselves! Kurt was awesome--we were simultaneously terrified and completely confident in his skill, which is the best of both worlds for me!
