If you say so. I drilled hundreds of wells in SE Michigan and trust me, a willow branch wouldn't have helped anything. If you honestly believe that there are water veins that vary as much as 38 feet in depth in someones back yard, I want some of that stuff your smoking!I have friends in Michigan who use dowsers. They use a willow branch and it not only finds the water, but the number of times it bounces, once you're over the spot, indicates how deep the water is. We live here in the southeast and although water is underground, there are places where you have to dig, and dig, and dig. There's a big difference between digging 45 feet and 7.
