While sipping my coffee, I notice that the water bottles which I left outside last night have quite a bit of ice in them
I guess it was colder last night than I thought. I'll save this bottle of water for later. During my usual hotter weather trips, it would be mighty refreshing, but not right now thanks!
The water bottles in my tent had no ice in them this morning. I've been trying to make sure that my water bottles are never completely full at night, just in case the water freezes and expands.
