I planned to visit four small nearby towns that I have never hunted this AM. The first town on the trip has a small park that two of my buddies hunted a couple days ago and reported finding some older stuff. Soooo..... I thought i better check it out myself. 
It didn't take long to find the evidence of their hunt. In fact walking around, I could tell who dug each plug. I started off popping some clad and then found a pocket spill. A kennedy half pockets spill! The first one I dug put a little 
on my face. Then I rechecked the hole before filling and got another good tone. After rechecking the second kennedy half fell out. This made me chuckle a little bit. So I rechecked one more time for good measure, and yet another good tone. Still chuckling, I dig some more, and sure enough a third kennedy all around 5 to 6 inches deep. I'm now laughing out loud. Nothing old (95,74,72) but still fun to dig. The next find about ten feet away was a wheatie. It had a nice green patina but the date was covered by a smooth black piece of charcoal-like material fused to the coin. It clicked it a few times with my thumbnail and it popped off revealing a 1916 D. Sweet, I'll take it! after stopping for a bite to eat, I hunted the area some more and found yet another kennedy half, 1976, about 30 feet from the first kennedys. I was having enough fun hunting this recently hunted out park so I decided not to continue on to the other three towns I had planned to hunt. I'll save them for the next trip I guess. I didn't walk away with any old silvers, but still had fun at this "hunted" park. Here's a few pics of the hunt, enjoy and thanks for looking. TC & HH, JJ

Good Luck and HH to you when you do a return trip.
(Sorry, that was bad) I think a more thorough search is in order, but am just happy to walk away with what I did after my buddies hammered it. JJ
