I had a similar incident a few years ago. I parked the pontoon boat trailer on the edge of my lot which joins the Army Corps of Engineers land at Kerr Lake. My neighbor came by on Thursday night making his nightly patrol and everything was o.k. I arrived late Friday afternoon and found this.
I called the ranger station Friday afternoon and told them what happened. The ranger said he would come by to take a look. I told him to bring his checkbook so he could reimburse me for the damage. He laughed and said o.k.
When he arrived, he said if I had damaged something on ACE property that I would have to pay for the damage, but if something on ACE property damages private property, then the private property owner is SOL.
Somehow, this ain't right.
