Al, if you can get a picture of that stone send it to my screen name at gmail. I'll ask him what to do if that doesn't specifically come up (or you aren't sure what the stone is made of).
I'll be there until Monday. Likely won't have signal there, but I can download it to my phone if you get it to me by Sunday night.
I don't have a good photo either
I have been having trouble figuring out how to get the cemetery cleaned up... It is a very old one, with just a few head stones (but lots of burials) that is currently in the middle of a horse pasture. (Not owned by anyone I know)
When I went out there to look it over I could only barely see the oldest one (the broken one) and it was face down. The stones have been covered over with thorn covered vines so thickly that I couldn't even reach the stone. My job this year is to figure out how to get it cleaned up long distance..... And figure out how to fix the broken and fallen over stone.
I did contact a cemetery society in the county in question (Washington County down in Texas), but they were no help on cleaning up the brush.
The busted headstone is a light colored grey stone, and is carved. It is not concrete. I really know nothing else.... So sorry.
Of all of the other headstones that I visit when I am in Texas.... None of the rest are broken (well, one had the little urn on top broken off), a few have some moss growing on them, and I have been reticent to scrape it off with a popsicle stick (which is what I think is correct?). One of the headstones had the deeply cut letters painted. It looks pretty good. My uncle had the local headstone business do it, I am not sure how well that weathers either, but it has been looking OK to me. One other headstone that I was starting to worry about was also painted by I have no idea who...and that turned out just great. They painted the carved vines green etc. and it looks good.
I am babbling.... Because I feel bad that I haven't yet rescued that poor headstone and cemetery....
