So we decided to give the Cache La Poudre hell today with the tubes and some pool rafts. Probably the scariest tubing, or even rafting experience I've ever had. To put it in perspective, what is normally a 2.5 hour run, took about an hour of actual float time. The rest of that was spent trying to rescue eachother. Only put one grown woman in tears from panic. Nobody was at any real risk of death, but it was pretty challenging on a fast flowing river.
Between my girlfriend and myself we lost six beers, if that gives you any kind of indication of the difficulty of the river.
