Get a free hot bath, groundcovers, and waterproof bags. Use 2 contractor's strength heavy duty black garbage bags. Use as waterproof groundcovers, mini-tarps or stuff sacks. Fill each bag with water, tie, and set it in the sun. Water heats up. Sit in one bag, loosely tie around your neck, soap up and soak out. Then step out and into the other bag, tie up, and rinse off. Enjoy your bath outside with nature!
