My 22 oz bottle that I haven’t used very much still has a price sticker on it. I bought this is 1996 or 1997 at an outfitter in Glenwood Springs, CO on the way to Canyonlands. $7.50 That probably doesn’t mean much but since I don’t have many things this old with the price tag still on them, I thought this might be a good place to put this information.
