Update: tombstone dismantled. it creeped out the wife. she said any time she'd take the dogs out at night, the moonlight would reflect off it, and any time the dogs would act weird, all she could see was the stones. she loves horror flicks, so those may have played a part in her imaginative frame of mind.
on a completely different note, we found a ton of scrap wood by the creek, and i built two extremely heavy benches this weekend.
