Late at night and low on gas, a friend and I are driving back to Denver from a road trip to Vegas. Somewhere west of Grand Junction we passed a car on the side of the road with a young couple leaning against it. We pulled over and rolled back to them. I forget what was wrong with their car, but it was more than just out of gas. We ended up towing them for about 30 miles until we found an open gas station. The extra weight almost caused us to run out of gas. Filled our tank, left them with a mechanic, and went on our way.
