Just after 6:00 pm today (Monday, 5-21-18), my dog alerted to someone at the front door. Seconds later the doorbell rang, and then the screen door was opened and the doorknob turned. I went to the door and met a young man standing in the front yard. He claimed to be representing a pest control company and was soliciting business. I have been a customer of that particular business for almost 20 years. He said he was just down from Idaho to help out the local company. When I challenged him, he denied having tried to open the front door and said he always opens the screen door to knock (even though he rang the doorbell?) Might be entirely legitimate, but when I went out to check our cars a minute or two later, he was nowhere to be seen. Tall, very slender young man wearing a Nike swoosh ball cap.
