Tim and I are using a 150 yard twine with stakes to grid out the area in the opposite direction...he gets one side of the line and I get the other and we walk toward eachother, then move the stakes two swings over when we get to the end. The first night we got about 4 passes in the rain and cold. We were in the trashy spot, but the next hunt is right in the belly of where the coins were found. Can't wait!!!
We have another bean field to hunt yet that had 3 houses on it at one point... We just can't drag ourselves away from the other site though..
Go get one of those conveyor-belt versions of the beach cleaning machines!
