When the phone rang for a shelling and sightseeing trip, I was pumped! That's what our wonderful National Seashore is all about! Not only did we talk some history of the Island, but we were able to see Green Hill, and the rest of the beach all the way to the jetties. Without a 4 wheel drive, this customer was unable to take his daughter and significant other down island, and that's exactly where we come in! Thanks so much for a great day David! Seeing a little girl's delight at the beauty of shells and ultimately nature are what the National Parks of this great country are all about!
