Once lashed down a float tube and all the rest of my gear to my mountain bike and rode the 2.5 miles to Lake Fontal. In the middle of a dry winter and all by myself. It was far from my most productive session of fishing. That actually make me stay longer on (in) the water than I should have.
By the time I hauled my ass out of the water, it dawned on me that I was borderline hypothermic. I could barely work my fingers to unsnap my fins. Somehow I managed to tie all my gear back on the rear rack of my bike. Since my hands and the rest of me were barely functional, I just kept my waders on and hopped on my bike and rode.
In some way, it was fortunate that I rode bike. By the time I made it back to my truck, my body temperature was back to normal, and I was able to get out of my waders. To this day, I still think the ride back probably saved my ass. That was back before I owned a cell phone.
