I'm interested in starting a group to log as many Masonic cornerstones as possible. There are tens of thousands out there, but I'm just not sure how to get started. The kid and I went out and collected the waymarks and photos for three today, but are now stymied. I began a group called 'Masonic Cornerstones'' but I can't seem to figure out how ...

RADON could also be a culprit. It's a gas and a century ago, it was probably strong as heck in granite mined locally. Here's a link to This Old House counter top conclusions... http://www.thisoldhouse.com/toh/article/0,,20241210,00.html

I want to find out where all the old cemetaries are. I want waymarks to cemetaries all but forgotten. Also any old abandoned buildings or paranormal, haunted like waymarks around SW Washington area.
