" . . . some guy in it tells me they're shooting the "XXXX XXXXXX" show, and I'm going to have to leave the area."
You know what, I have fished in tournaments, although I prefer fishing just for fun. However, if somebody in a tournament, or a tournament official, ever comes up to me on a lake and tells me I have to leave, I'll remind him/her that this is a PUBLIC resource, and that the tournament organization is making a profit off of a PUBLIC resource.
I'd tell him he has NO BUSINESS/Authority ordering me off a public resource. Then I'd get the tournament director's name and phone number, report this idiot, and threaten to contact the state wildife agency, local officials, etc. Believe you me, the tournament director will freak!!!!
Then, MineralMan, I think I'd of stayed in that spot just to aggravate the idiot. I'd hold a rock throwing contest or something (not at the anglers, but in the spot they are fishing). Heck, I might even have to go wading, swimming if the weather permits. I've always wanted to be a movie star and this would be a good chance (grin). This guy was WAY out of line, and I can't think of any tournament director that would condon his actions.
On most major reservoirs, where big tournaments are held, there is no permit required (except maybe to launch your boat).
I was going to suggest you also take a leak off the front of the boat....until I read your screen name, LOL!
