A loaded van pulled in to the only remaining campsite. Four children leaped from the vehicle and began feverishly unloading gear and setting up the tents.

Two of them rushed to gather firewood, while the other two and their mother set up the camp stove and cooking utensils.

A nearby camper marveled to the youngsters' father, "That, sir, is some display of teamwork."

The father replied, "I have a system... no one goes to the bathroom until the camp is set up."
