Yesterday the head of the athletic department at the local high school called me and tried (unsuccessfully) to convince me it wasn't a high school coach or class involved in the trespassing incident that damaged our front lawn. After talking with him, I faxed the school district additional information proving I knew perfectly well who had victimized us and that we could identify them.
This morning I finally got a call from the coach admitting he was the one who did this to us. After admitting his guilt, he tried to convince me the students involved weren't wearing official high school attire; I told him I was aware of what student athletes are told to purchase and wear for official practices and that this was what the students involved were wearing. He then tried to tell me he didn't know what his students were doing as "his back was turned". I told him this simply wasn't true, as both my daughter and I could attest. (He also admitted that another person present that we'd thought was a student was actually another coach!) After I asked for an apology, he did reluctantly give me a simple "I'm sorry".
This coach also admitted to me what I already knew: his parents own property that adjoins mine to the north-northeast.
UPDATE: This same coach followed me while I walked my dog the next night, and he was waving, grinning, and laughing to make sure I noticed him.
