That mouse thing in the can was nasty!! Thanks Mutt for a picture I won't be able to get out of my head...
Whynot, you're correct, I could probably wash & then boil water in the canteen to clean it. I wanted metal for that reason anyway - I may buy one just to try and see how it goes. Plus, I know this is probably weird, but I like the metallic taste of a metal canteen. It reminds me of hiking at Mt Rainier back in the days when you could fill your canteen from the waterfalls & rivers. Now they're all polluted.
Sorry Techno...I came across that video when I was looking at the metal canteens for the BOB, and it just stck with me. It was the main reason I decided to go with the clear plastic style.
