Personally, I wish permanent blinds on public waters would be outlawed, plain and simple. They are an eyesore, a hazard to navigation, and are a constant source of fights and arguments. In a sense, they are also littering.
For some reason they bestow on folks a sense of a private lease, which is a fallacy. But, this lends problems to people who hunt public water but don't want to erect an eyesore - especially when blinds are built where perfectly suitable shoreline cover exists. I have had many shorelines and points that I hunted frequently using natural cover ruined because somebody built a blind where one wasn't needed. Up here on the upper coast, birds will avoid the area all together. On the middle coast around Rockport, you can usually shoot birds out of blinds year round - but the birds learn to skirt them, providing for longer shots on the average.
The airboat guides are particularly bad about them, even to people who didn't squat in their blind, but set up near it. I have had decoys run over, been cussed, been peppered, and been threatened many times. These are times when I was there an hour before they showed up. Many times, they weren't even hunting and were still upset! Heck, I even had an airboat come park right in the middle of the spread and walk off, saying it was our fault we set up where he liked to park his boat. I've had other non-guides do those same things, but 3 out of 4 times it happens, it is guides. To be fair, ONE time, and this is the only time, I had a guide track me down at the ramp and apologize to me for the actions of his partner that morning when he heard about it. I was floored.
Now mind you, it is very rare for me to set in a permanent blind on public hunts. I'd say I do it only once or twice a year out of 40 hunts. I find them a detriment. Yet, I still have to deal with the blind owners.
It would be much easier to outlaw them, and allow people to hunt using temp blinds, boat blinds, or from the shoreline. I'm sick of not being able to take my kid out on public water because I might have to argue with some yahoo who showed up late and was upset that a spot I like to hunt is in the same cove or pond as his blind.
