The permit process has changed, but I can't honestly remember if there is a minimum or not anymore. It's supposed to cover ALL organized events at a MDNR boat ramp. Spitler would remember, but he seems to have disappeared on an extended vacation or something.
I like what Mini said. You have to try to communicate and work things out first before you start 'shooting.' It's hard to do at times, but probably best in the long run. Many Northern states now have a tournament permit process, so it shouldn't be too surprising to anyone anymore...
except maybe ole' Ben Trodder. He doesn't seem to get anything about anything. But he sure get's around. I see him all over. He's a master of disguise. He looks different and often has a different boat, but it doesn't take long to recognize him from his actions. Often, once he know's you're on to him, he'll up and take off to 'visit' someone else.
