Dad had his own way to set about the task. He decided that he needed to set up a grid to tell exactly where he had already searched. Mom and I were there to provide the "feet" to keep the grids in place.
Sticking rods in the ground to try to locate the water shut off
This was an interesting process, but I'm glad he was able to locate it so he can get access to the shut off valve for the water on the pier. YAY DAD!!!
