Dusty, I'm not going to waste your time and mine. If you can truly pull this off, you should be collecting your cool million from James Randi.
Let me suggest a (literally) blind test: Have yourself blindfolded and led outside by an assistant. Have the assistant point you in the general direction of a buried line or whatever it is you think you can locate. Don't peek, you're only cheating yourself. Have your assistant tell you when your bent coathangers cross or uncross or whatever it is they do. Then start digging. Let me know what you find, be it waterline, pet cemetery, spring-tooth harrow, mastodon tusk or buried treasure. Don't give up! Sooner or later you're bound to find something. When you do, you'll know you're ready to collect your million dollar prize.
