For some reason . . . your post reminded me of Garrison Keilor’s LAKE WOBEGON narrative this weekend . . . I know, he’s a clueless liberal . . . I was on a long drive home and I sometimes enjoy the humor.
About the swamp gas, I had always heard that it bounce around. I was deer hunting just before daylight (sitting in a tree in a light misting rain hoping my husband would come for me soon actually) in Brazoria County near West Columbia Texas. I saw a bright glowing light and I immediately thought someone else was in the woods driving around. Then the light came down and bounced up about 20 feet, came down in a arch, hit the ground again and bounced up out of sight. Someone had told me he saw the light (called Bailey's light after an early settler) when it bounced on fence posts along side the road.
