Every year I do a cemetery in my yard, using many store bought tombstones. This year I am tempted not to do it because I'm so sick of struggling with those cheap little plastic stakes that come with them. They seem to break the minute I try to set them up. (The ground here in AZ is pretty dry & hard) Does anyone have any suggestions as to what I could use? I have about 20 tombstones and no stakes! Thanks for your help.
