After hours in a gua gua and a painfully expensive taxi ride we arrived at a cave famous for its taino art work and... it was closed. Fortunately, our taxi driver convinced the guard to let us in if we bought a flash light and batteries. It was awesome! It was pitch black and we would shine a flash light on the wall and it was full of paintings. It was really really fun and I thought it was cooler with the lights out than it would've been with the lights on.
