More: Johnny Cash, “Dog in Black” , loves everything outdoors! Boating is his favorite , as well as exploring Coosaw Island in Beaufort SC, and finding as many sticks as possible! One of his favorite toys is a big sweet potato; he is quite possessive of it! He loves to ride around the island in the truck and the Tracker UTV, but at night he is just a little puppy again, curling up beside us to go to sleep!
