I was given a couple old 20LB propane tanks. I exchanged one of the empty ones for a new OPD tank for 19 bucks. Then I filled up a fuel can so I have fuel for my generator this winter and I filled up the tank on my ATV and winterized both.

I wished I had paid attention to the second propane tank. Its almost full but with the old valve it won't work on my grill or in my Camper. I hate wasting propane but I can't do anything with it. I didn't even think about it until I got back home.
