Kanoes,

Does the sunshower work good for you? I tried once in the spring on our first trip, and it didn't seem to make that big of difference for me in temperature. Maybe I need to try it again. Although, it is nice to have your hands free for the rinse cycle; we have had to help each other rinse off lately.  

Generally, I have just waited a couple hours after scooping water from the lake to let it warm a bit. If it is real cold we might heat some water on the stove for rinsing your head.
