I've tried two different ones and our High Sierra hard pan killed both of
them. :) The top of the rods mushroomed nicely and the hammers got nice
and hot, but the rods stayed half-in and half-out of the ground. It took
two laborers with sledge hammers an hour to get one rod the rest of the way
Beautiful country up here, but effective grounding is a real nightmare!
