We took Mom to the airplane beach (Maho) to watch the large jets come in for low landings and sandblasting take-offs. We were sufficiently thrilled. As we passed this dire warning, mom and I laughed about us exposing our "old mother" to something dangerous and how irresponsible some people might think we are after seeing this sign. And in fact, one of the jumbo jets turned for takeoff before we expected and we got blasted with sand. We were supposed to be out of the line of fire but never anticipated the premature turn. There was a plane on approach for its landing just as the jumbo jet was getting ready for takeoff so we thought maybe the big guy got in a hurry. We had sand in our hair, clothes, everywhere. But we all thought it was great fun.
