Bloke and I have been saving our crushed aluminum cans for quite a while. Five years or so I would bet. I did some clean-up at the hangar this morning and filled another garbage bag with crushed cans. There are seven bags here in the corner and a couple more big bags under the stairs. We are going to (someday) take them in and get some money for them. Should have done it last year when the aluminum scrap price was much higher. I guess we can wait another five years if we have to.
