As a teen, there was nothing better than finding a used mag in the woods in the uk. There was a huge thrill in finding a ruin mag that had most of the pages stuck together, then suddenly finding that group of pages that were " unused" and ready to shoot on. Mate and i used to go round the golf course looking to find lost golf balls in the rough and used to occasionally find mags. A couple of times we dissapeared over the wall next to the golf course where it was derelict steelworks and lay a mag out and both shoot on it. great times
