Field about 50 acres belongs to the park. No one goes in that field. All summer the weeds are 3 feet tall, but they cut the weeds in the fall (maybe for the horses) so weeds are short now, like a lawn. Been there about 5 times when the weeds were tall, found only a British colonial penny. Tried it again today, got there just before the snow started to come down heavy, stayed about one hour. Seems like coins were popping up everywhere today, but I had to leave while I could still drive home. The 2 center (1864) was found yesterday across the road. Today I dug the 1904 IH, 1917 Merc and the 1810 half reale. Fifty acres is a lot of ground to cover, gotta go back and try again, hope to find more old silver. New Jersey. CoinStrike.
