My Grampa had a story about doors and hole for sturgeon spearing.
Sometime in the 1950s I think, a warden had the habit of sneaking up and throwing doors open and charging in. Trying to catch someone fishing for walleyes while watching for sturgeons. Totally violated all common courtesy practices and really trashed your vision for a period of time. One of the fishermen on the Brothertown side moved the hole to immediately in front of the door. Of course the sneaky swampdick took an unexpected dip. I do not remember how the citations played out. I do remember Gramps saying the man learned to knock.
I also remember a hole on one end of the shack, sitting side by side looking down the hole. A spear on each side. The door far from the hole.
