Perhaps one of the most exhilarating experiences I had (and one of the few for which I have pictures stemming beyond just landscapes) was whitewater rafting in Montana. Glacier National Park is the most beautiful place that I have ever visited, and whitewater rafting through it provided an even more spectacular experience.
Overlooking the fact that the air temp never made it to 60, the water temp
was 38, and I had never rafted before, one can easily see how great this felt.
In these pictures, I am in the very front of the boat on the left (the "leader
position"- everybody in the raft took their stroke cues from me). I was
very cold and very wet by the end of it all, but WHAT A RUSH!
