I met him on the square in Decatur and we did (or tried to do) these:

This was the cleverest cache I've found. Yellow Jacket is an absolute wizard; I bow (deeply) before him. On the cleverness scale of 1 to 10 this one is a 10. Honestly!And it's a terrain=1 (less, actually)!
This one wasn't there. It's not that we couldn't find it (we couldn't) but a youngster who knew about 'cachin' told us it had been taken. He confirmed that it "used to be" where we'd concluded that it must be -- but it's gone now. Hope the owner puts a new one there; love to visit this unique spot again.
This one is in Oaklawn Cemetary (where a lot of famous people are buried). This person is one of the top one or two: Bobby Jones.
It's amazing what you can find in cemetaries. Nice virtual. Wasn't able to figure out the answer to the third question but hope the owner will give me credit for the first two.
This one indicates that the area might be swampy. Heck, it appears to be in a FLOOD PLAIN! Muddy, muddy walk (took me a half-hour to clean my boots) and reminded me to ALWAYS go 'cachin' with a garbage bag so the boots don't impact the auto carpeting on the way home.
The clue was good and we found it handily. T/L nothing (well, Rich did take a leak; I guess that counts as both taking and leaving something).
