Why are there so many on here claiming some kind of moral high ground by saying "know your boundaries! and nothing else matters!"
I find it strange that many here are making the huge leap that if:
You support some type mandatory private land postings you somehow support willful trespassing on un-marked private property on a the technicality of "well it isn't posted, so I can hunt there." That is just as ridiculous as someone who subscribes to that practice.
We can all agree that:
Un-Posted/ Marked Private ground DOES NOT make it public or give anyone the right to go there.
Each individual should do his/hers best a knowing where the boundaries are. And should have a means of reference (GPS, maps, etc) to ensure compliance.
I sympathize with you landowners that have or have had issues with trespassing in the past. However I would caution you, that if this passes I could make a strong argument that those problems would get worse before they would ever get better. And yes, marking property is a huge pain in the ass and yes some bad apples will still choose to ignore it no matter what you do. But I feel the whole intent of the law as its currently written is to make a very clear border of whats legal and what isn't. Thus making potential violations very clear. If you decide to forgo that, suddenly there is even more gray area. Which will cause more confusion and more frustration and less hunter involvement. This law was written for the convenience of the public at large at the inconvenience of the private property holder. Now a large enough private property holder is trying to legislate their way out of that inconvenience and put it on the public. Which is their right to do so.
To those worried about the "fringe" areas of the boundary lines. Keep your GPS tracks on and keep it handy. If you are confronted by law enforcement, show them your GPS tracks, show them the border lines. Show him you are doing your best to stay on public. I've heard several cases where an individual was accused of trespassing by a landowner and was confronted by law enforcement. He showed his is tracks for the day and the officer said "thank you very much" and went on his way. This way you have evidence and all the other party has is a story. This doesn't cover all circumstances, but it at least show you didn't have malicious intent.
