After watching numerous tournament fights on YouTube...what are the fishing location rules?  First on the spot gets it or who ever was there previous owns the spot for the whole tournament?

I believe it's fair game to everyone and anyone who wishes to fish that spot. 

The lakes are public and no one owns a spot. I've seen two pros agree to fish right on top of each other and I've seen pros cuss and swear at each other over a spot. When it comes down to it, they can both stay or leave. No rules about it. 

Also, regular non pro anglers have a right to that spot as well and can fish it even if a pro is fishing it in a tourney. It's a jerk move, but you can do it.

Not to be snarky but there was just a Loong post on this subject and I think everybody made their thought perfectly clear.
