So sorry guys, but this is where I take the left fork on the road. I carry just the amount of water I think I will need. Sometimes with no more than a quarter tank of water. Why carry around extra weight. I know I live life dangerously, but I also don't travel with a full tank of gas, or carry the kitchen sink with me. The lighter the load I have to pull, the better. This lifestyle may not be for you, but I live life on the edge.
