Stone Harbor - Curious, for at least the last 3 years I notice Stone Harbor beach tag checkers walk 2-4 abreast up and down the beach. In those 3 years, I have only witnessed once where they actually approached someone on the beach presumably to check to see if they had a beach tag. We have never been asked or approached, and I don’t know anyone that has been. So why make them walk up and down the beach in the hot sun. Fortunately, they are smart enough to walk along the water’s edge to keep cool.
