I love signs, especially when they're funny or don't make sense.
This was taken last summer while staying at an obscure resort. Went for a walk around the small lake. Standing on a gravel road, less than 20 ft from the water. Not a cabin or home in sight. Across the road is state owned land. Nobody to claim the shorefront. Water so shallow, you'd have fun launching a canoe. Half mile down the road is a public landing. Not sure who they were trying to keep out. Deer?
