Went to the bullet hill after work today. Have you noticed that when kids bike a route through the area they wear the dirt down. We are finding good items at depth ergo when dirt is eroded by bikes the deep items are closer to the surface. With this in mind I crossed the sidewalk at the hill with socks, checked the bike path and found another three ringer just one inch deep. It was so obvious but we need to open our eyes. I even skipped this till this day. We always look for ground disturbance, sidewalks removed, erosion and other construction but this time had our backs to the easy one which is mine now.
