wateryglen, you make some excellent points. My comments about reporting to the authorities were based on the original comment: “A friend was riding on the Singing Woods trails today and someone had strung barbed wire across the trail.” I don’t know the area personally, but the comment led me to believe that “Singing Woods Trails” was a publicly accessible trail.
Trespassing is wrong, and ignorance is no excuse. You are right there. However, two wrongs do not make a right (but three lefts do). Landowners do not have a “right to do whatever they want” They cannot set up hidden traps designed to harm or kill people any more than they can sit in their yard and shoot as riders that cross their property line. Yes, homeowners also get frustrated with the authorities - it is much harder to catch the anonymous rider that is long gone when the cops arrive than it is to catch someone doing something on their own property. However, if they put up barbed wire or some other “trap” and someone gets killed, they are technically guilty of pre-meditated murder (whether a DA will push for that is another issue).
There is a civil way to handle these things. Just as it is the rider’s responsibility to “get permission” and “not get indignant” it is also the landowners responsibility (morally and legally) to mark his border and post signs.
In fact, if people are laying barbed wire traps (especially on easily accessible private property that is not marked as such) than I bet it would be VERY easy to involve the authorities to resolve the situation. If people are going through the trouble of setting potentially deadly traps on their land, I would NOT recommend ringing their doorbell, as a “friendly” conversation on the topic doesn’t seem likely.
