IMO with todays electronics and technology, the odds of you or your boater fishing a spot that no one else knows about is pretty slim. In most cases, that guys "spot" is someone else's as well. With that being said, you might ruffle some feathers if you show up to the tournament, and run to spot that a guy you fished with previously told you that is "his", and he finds you there. This whole deal about fishing peoples spots isn't very clear, and everyone has a different opinion. With that being said, water is water, and no one owns any certain spot. I do believe however, telling people about a man's brush pile that he sank personally, that you have never seen anyone else fish is not proper respect, but then again, the majority of brushpiles were sank by someone, so technically you are fishing someones spot. I think it would benefit you to find some of your own "spots" and learn them inside out, and master those spots depending on the conditions. Be respectful and communicate with your guys. Ask them if they would mind you fishing "their" spot if you pull up and aren't there. Even if they say no, you asked.. At the end of the day, your entitled to fish where you please, just try to be respectful to others
