I heard there was a guide around Paris Landing that got smart with a man & his wife for fishing "his" brushpile. You would think he would know better and have handled it better.
Many years ago, a boat from Illinois tried to go between me and the bank I was fishing. Since I was sitting in about 5 feet of water and throwing into 1-2 ft. of water, I knew it would mess up my fishing. I moved in and cut them off and as they went around me, we had a very pleasant conversation. I don't think they realized what they were doing. Trouble is, I wound up spooking the fish I had been catching trying to stop them from doing the same.
Some people are ignorant about proper etiquette on the lake and others are misinformed or just bullies. This same buddy was fishing a treetop with his son several years ago and had a guy pull right up to the same treetop and start fishing. It's easy to say you should give someone down the road but the problem is we don't always know who we are dealing with. Things could escalate in a hurry.
There are several ways to deal with someone who wants to homestead a brushpile regardless if you got there first or not. I've never had to do this and hope I never have to. I go fishing to relax and not get stressed out. Good rule of thumb is to never wrestle with a pig. You'll only end up getting dirty and the pig likes it!
