Surprise call today. A call from Joe asking if I could help him locate the sewer covers for his cesspools. He knew about where they were but not surer how deep. He had a metal detector from a friend and just could not get it to work. I meet him at 2 PM and spoke about the possible locations for the two covers. They are make of steel and in a parking lot. I found the first about 10 inch below the gravel. After more than an hour and a half in the 32 degree weather. We called it quits. Joe thanked me for coming over with no notic and in the freezing cold. Thank you Joe for the gratuity.
