Lancair Lancair 4 (N381TS)

A flight plan for Saturday, 2-22-20 at ERV shows this plane flying a large loop to the NE then several small, tight loops across my ranch. What could be the purpose of this flight? On 1-7-20 this plane, which is very loud, flew low over me while I was feeding my wildlife, two times--15:42 and 16:03. Then on 1-8-20, he showed up again, harassing me while I was out in my yard working, at 11:49, 11:51, and 12:15. Mr. Small has a very nice airport in Fredericksburg. I wish that he would consider harassing property owners around that airport in the future.
