We rented a cart last time from the guys right next to the Beer/Coke distributor,and we took our cart as far above the ferry as it would take us! Then we promptly ran out of "gas" at a bar on the beach! 2 0r 3 Belikins later the cart guys showed up with a new/fresh one and they drove ours back into town cause the "Belikin pause" had allowed the batterys to charge back up!
Moral to the story is , 2 or 3 belikins will fix most anything!
Did cost us an extra $10 for the other cart on the ferry though!
Looks like the cart path goes north of Capricorn too......Richard
