Back in the 1970s went I got out of the Navy,I used to coach football at this sports park.I decieded to take my Ace 250 and check it out! Well first quarter out of the ground was a 1965,missed silver by one year.I only stayed about 1 Hour as the grass was not freshly cut ,about a foot and a half! Still managed $3.75 all quarters in a space the size of 10 yds. I have about two acres when the grass is cut.I know there will be silver here as park has been here since mid-1800s. But being a 2hr ride it will have to wait for spring. I dont remember ever seeing any one with a metal detector. HH Wayne
