I am like many here in that I don't do single use plastic bottles. I like using small convenience stores 'free' cold water and spend my money on their munchies. When water taste nasty (C&O canal pumps), I just use some flavored electrolytes. Now hot water after riding in this current weather sucks but if you're thirsty you'll drink it. I did on Sunday, ugh. Wet underwear, hmmmm, don't know if I can do that.
