I spent a summer as a seasonal Corps of Engineer ?ranger? (aka Park Technician). Every weekend one of my main jobs was going around putting out campfires people had left. I was to put out any campfire left unattended, not just the ones where the campers had completely left, including those where they left to go fishing or some other task. Let?s just say that after I put out a campfire, no other fires would be lit in the campfire ring since it was usually swimming in inches of water! Our ?real? rangers took an exceedingly dim view of unattended fires since they had to fight far too many fires resulting from a blown spark. We were very direct with folks checking in, and they could never say they weren?t warned, but I still got some irate visits. Tough luck dude.
