Short hunt after work

I went to a neighborhood park after work. Hit an area next to the concrete slab that was once a basket ball court. I have pounded this to death with my AT gold since I found a 1964 Washington and several wheats. I figured this would be a good place to fire up the Dirty Thirty and see what I missed. I found a Rosie and 5 wheats in about 5 minutes. I guess I need to go over the entire park again
