.........THE PADRE ISLAND NATIONAL SEASHORE PARK is more or less in the middle .....portion of the Northern side is open also the Southern side with entry thru Port Isabel.......some of the really good sites are only available with a 4 wheel drive vehicle so take plenty of water and gas........from Port Isabel entry....there is about 60 miles of Island before the National Park......most of this is UnPaved.........NOW THIS IS FOR THE REALLY OLD COINS NOT ANY NEW DROPS FROM SPRING BREAK.............JOE
