Found the one near the cache at your home, I believe anyway!! I have a hard time finding the correct ones on the listings when I do find them :(. Thanks for the event!

I looked for all 3 marks but didn't want to hop the fence and go on private property. I did however find the azimuth thanks to GEO*s coords. It was an easy find and the mark is in great condition.
