I hear ya. We lived on an ox-bow lake that was once part of the river. We had riparian rights to use the water. The entire lake was bordered by a public park, a cemetery, a historical landing (where LaSalle portaged between the great lakes and the Kankakee river), the county(later city) and 4 homes, including ours. It had over two miles of shoreline. The four homes all had steps down the steep embankment and we had landings for swimming, boating, etc... The public park had no swimming signs posted. Every year, some new park policeman would try to arrest us kids for swimming. We'd have to explain that we had water rights. They wouldn't believe us. We'd kindly disregard their orders to leave the water and tell them to talk to our folks and give them the address and phone number. Many times we had the police over. It was quite amusing. We usually ended up being pretty friendly with the park police the rest of the summer. A friendly wave as they patrolled.
Anyhow, many times we had to call the police for people trespassing that thought they could walk around the lake. You have to understand the a quarter of the lake was a sheer 90' escarpment with barbed wire on our property line that they had to climb over, under or through, frequently damaging the fence. I learned a lot about private property, permission and respect from my parents. That's why it cheesed me off that people would come onto our property and intentionally run down rows of trees, use chainsaws to clear trails on my property, nail signs onto my trees and leave tire ruts that caused massive erosion on our sloped sandy soil. Despite the no trespassing signs and the clearly marked snow mobile trail, it was getting worse and worse. So, yes, a few bad apples spoiled it for the rest of the folks that followed the rules.
You'll be happy to know that I do allow hunting on my property by permission only. I find that hunters with permission tend to keep an eye on my place better than I can. They want a place to hunt and won't tear up the place. And they give me some of the meat from the deer from time to time. :licking:
