After the I saw the observation post I checked and their view was blocked by the vegitation. After they cut a hold in the vegitation I parked my pickup to block their line of sight. They could still see thru the passenger side window and a part of the windshield with a part of the door post in their way. I then applied a large towell to the passenger side window and a sun blocker on the dash to block that part of the windshield so their view was totally blocked. Five minutes after I finished my other perp neighbor (lives on the other side of my home) drove up to his mail box and spent several minutes there looking at the pickup while making a phone call. That should block their view and hopefully any electronics they had aimed at my home.
