I have to agree with those arguing for too much enforcement. Is there very limited enforcement in northern WI? Yes. By that I mean, you rarely see them around on a consistent basis. I understand that. But when they are around, they go OFF the DEEP END with checkpoint enforcement, and that is simply un-American and communistic. But then again, the DNR answers to nobody and you basically can't challenge them in court, at least not easily.
As some have already said, you should NOT be stopped for any reason, unless you are clearly violating rules and regulations, or have broken a law. If you have stickers, are stopping at signs, and aren't riding recklessly, they should not be harrassing you - period.
Now on the other hand, I was in Eagle River area for 10 days between X-Mas and New Years. I was coming into town from the north, just north of Trackside and I was in a hurry to be at Track by noon. I looked up, saw the Trackside sign ahead, and slid through a stop sign with nobody around, except the 2 DNR guys just a few yards off the trail. They both chased into the parking lot where I was apologetic and cordial, pleading my case for stupidity. The kid said, "you would have blown right through that sign if you hadn't seen us". I said, I don't normally do that, and explained why I had. They gave me a warning, and took my name and registration. I thanked the guy and shook his hand. They aren't all jerks.
He could have given me a ticket, but at least he listened to my case and used sound judgment for no harm, no foul. I'll tell you what, when you get pulled over for something stupid, it sure makes you think about following the rules and avoiding the hassle.
