I rented a cart for a week back in January. It was gas. I drove for hours each day, and in fact went from 466A all the way up Buena Vista to 42 at the north end of TV and back to Liberty Park. I drove to LSL, SS, Target, Colony Center, and just went for rides as I smoked cigars.
Still had better than 1/2 tank of gas left when I was done.
I think I will be buying a gas cart because I have a real paranoia about battery life. I worry when I sit with my car off and the radio on. I have concern using a flashlight excessively. Maybe I should see someone?
I know it's me, but I just don't want to get stuck. I'd be a bag of nails of that light came on while I was driving!!
