Hey everyone. Years ago I built some gravestones out of plywood and attached a 2x4 to the back of each one with some nails to secure them into the ground. Well after years of sitting out behind the shed through winters and all kinds of harsh weather, they're truly rotten and crumbling, and they look FANTASTIC! Next year I'll probably look into replacing them, but until them, I need to find a new way to secure them into the ground seeing as my dad hates it when I dig holes into the yard for the plywood. They aren't the strongest things ever seeing as they've literally begun to rot and have succumb to termites. Any ideas how I can get them to stay in the ground?
