When I was about 14-15y/o, I was rabbit hunting with my Dad, uncle & 1st cousin in the Chicot Hills of central La. Today this area has a large Boy Scout Camp & alot of homes, but 30 years ago it was all forest. We had walked a couple of miles following the beagles, but really not hunting seriously. Eventually we came into a small clearing (maybe 1/2 acre). In the clearing saw 2 things, a newly blown down tree & a small brick pier (like something under a house or porch). It was about 12" square, 18-20" tall & covered with a green moss that grows everywhere in La. Dad & my uncle said this clearing was probably an old homeplace. Dad, my cousin & myself sat on the tree & my uncle sat on the pier. Dad & my uncle smoked a couple cigarettes & my uncle was flipping his pocket knife & sticking it in the ground. We sat & talked about 20 minutes, then started walking in direction of the dogs. We'd gone about 100yds & my uncle realized he'd forgotten his knife, so we walked back to the clearing to get it. When we entered the clearing we found the tree, cigarette butts & the knife stuck in the ground, but the brick pier wasn't there. There wasn't even an imprint in the ground where it had been, it was like it was never there. We could see where uncle's boots mashed down the grass. No one was able to explain to this day just what it was that we saw & my uncle sat on. Dad & I tried to find the clearing a couple more times after that, but never could. My dad & uncle are gone now, but my cousin & I still talk about it every now & then.
