I made the 20 mile drive to the county fairgrounds this am with dark clouds threatening rain. As luck would have it, I parked the truck, pulled out the MX5 and started detecting. Less than two minutes after starting it was raining. I headed for a pavilion close by and waited for the rain to stop. I watched the mud puddles for the rain to stop and when it did, I crossed the road and turned on the detector. In one minute or less, I got a wisp of a signal, with a number of 90-91 flashing. Many times this is silver on the MX5 and it was this time too. 1940 mercury dime. The rain started again and I headed back for the pavilion to wait it out. Waited about 10 minutes and it almost stopped so I headed for the mercury dime spot. Ten feet away, another deep sounding signal in the mid 70's. A wheat penny and the rain started again. After another 10 minute wait, it stopped so back across the road I go. Minuted later a lower tone (I use 8 tones) with a mid 60's number. Again it was a deeper coin, but this time it was older. 1890 Indian Head from about 8 inches. It started raining again so this time it was a 15 minute wait. I could not pull another good coin, just a new quarter surface drop. After this, I called it a day when the rain resumed. I hope I can pick up where I left off the next time, but today the stars were lined up. I had given up on this part of the fairgrounds, but we had a tremendous rain storm last night and the ground was saturated. I will probably spend a day here next week and not find a thing, but a day like this morning is why this hobby so much fun.
