Well it appears I made a "grave" mistake the other day when I was at the local picking transfer site (garbage dump), there were some head stones laying in the concrete junk pile. Replacements it appears as some corners were broke off, some edges chipped, etc. No, none had my name on them!!!
The thought did cross my mind,(didn't take long, small area), maybe a good simple close enough for some jobs surface plate. Alas, I did not even take one. Next time maybe.
The biggest problem is the availability of a lifting device.
The second biggest problem is hoping its still there for next trip.
