Oh and wanted to add (although I know all cemeteries are different and have different rules for what can be in the ground and on the grave stones...because of mowing and lawn maintenance) maybe you could go and get a small Shepard's hook and that way you can hang some flowers on it. Also my mom has a small (like real small) flag holder pushed into the ground right beside my brother's stones and she hangs different flags on it (holiday ones, ones for each season and even birthday flags that she hangs up on their birthday months), perhaps you can find one like that and use it. Those things don't replace the stones but at least you could have some better things to mark his grave in the mean time!!!
