Lots of conflicts in the Skagit flats. Welt's property, especially. Birders line up their cars along the road and glass and when the parking lot fills up, the overflow gets contentious. I have attempted to at least say hello or acknowledge the birders, but, most have literally just ignored me or looked at me like I was doing something wrong.
There are also folks who follow the snow geese. Back when they had the snow goose access program, I was able to score a couple of days on some great fields. If we were into the snows, the birders, tourists, photographers would park along the road and enter the fields to get closer and get the birds moving. Really limited the shooting as it ended up not being safe sometimes.
Also had issues with fishermen in potholes area while duck hunting. We have had many fishermen come in and fish just outside of our decoys or off the banks in the seep lakes. Not an easy scene when the other party knowingly is messing with you.
