Once I was backpacking in the Cascades with a group (my family isn't quite into going that far
) and we were above the line where snow fell in June. Anyway we stopped to eat lunch, look at everything pretty, and then roll our eyes as the leader decides it is time for an "ice breaking exercise." We take off all our spare clothing so we are standing barefoot in only shorts and shirts and line up on a little snow covered log. Then we are instructed to take a step.
I have never felt colder water in my life.
