I went to his house because he wouldn't return my calls. He said he'd call me back and I waited until the next day. I went to his house, he asked me who the F I was. I told him I had a motor there and he told me to get the F off of his yard. That I was trespassing. He told his wife to call the police on me and he just kept screaming get the F off of my yard repeatedly so I left.

His son brought it by, and I told him how his dad treated me, and he said, "well we do have no trespassing signs."
