I went to the old fairgrounds for an hour with the intention of digging only perfect 180 signals. Just to save energy and maybe being able to detect a little longer. But the 100 deg. temp and the 72 deg dew point got the best of me. I dug one signal that turned out to be a small piece of wire that I knew deep down wasn't a coin, but I had to dig at least one plug. I was red faced and squirting water out of every pore so I called it quits. Oh well there are better day's ahead.
Good luck Gary
