We found a massive stash of em when we were kids and we spent so long going through em that we actually got caught off the perv who put em there.
Must have been over 100 mags and they were left in under a big wooden door to keep the rain off em
Used to find loads, usually around an old den in the woods or around one of the ponds, but then I was out everyday. Not like the lazy shits today that never go outside. Rain/snow/sleet/wind/sunshine, it didn't matter, we went out anyway
Maybe that's through living with countryside all around you though
