Did you ever run out of gas before reaching a gas station?

I was on an interstate towing my RV and passed the exit just before the one I was to take. Just then the low fuel light came on but thought I would make it. I just saw the exit ahead when the engine started to stall and coasted to a stop. So I walked up the ramp to a gas station. Got gas, walked back to fuel the truck. Fortunately a state trouper came be and had his flashing lights to move traffic away.
