Cadillac Shack which is the smallest of the shacks.
The large grey building in the back is the Cotton Gin where we were parked (but on the right side and out of this picture). The Cadillac Shack is at the end of the Shack cluster.
Hope I get this next story right ~ the Blue Bottles hanging on the post outside the front door are there to scare away the Hake's (pronounced like "cakes"). The wind gets trapped in the open bottles, moves them or whistles and scares the Hake's. This is an old superstition of the Black Community.
