You'll probably think this is pathetic, but I live in northern Nevada, which means I live on a giant rock broken up by bits of soil. All my tombstones have the same re-bar spacing, so once I found places that I could actually pound the re-bar into the ground, they stay all year 'round. Yes that means my tombstones return to a set pattern each year, but I have enough (and am planning more) of them to rotate. During the off-season, each piece of re-bar is wrapped in geology flagging so no-one trips over them. I am also lucky that this whole setup is in an unincorporated section of my yard. The biggest pain is mowing around them - guess how often THAT happens! HM
