I am training for a 50k Ultra Trail run this summer and on my way home noticed a couple of houses with dirt yards. Went home and got the Etrac ..no one was home at the first house. Stopped at the second and there was a retired man sitting on the porch knapping stones. I BS 'ed with him and he gave me permission to hunt the yard, but only the dirt part...45 min. later I ended up with this...great silver to wheatie ratio.
