re: Trespassers and what to do

I put No Trespassing signs up on the sand bar along with survey tape across the property line. He continues to ride the creek to our boundary and makes plenty of noise at about 4:30 pm, (prime time). He has done this for 4 days now. I have been unsuccessful in "catching" him in the act. I called the Sheriff's office this evening and they are going to meet me at his camper trailer tomorrow after lunch. I have also enlisted some land owner/neighbors who own creek frontage for a show of force. Hopefully this will put an end to it. We shall see.
