You’re on your way to a mountain-biking trip in the desert of New Mexico. You gaze out the van window, starting to fall asleep as you watch the dusty, flat landscape. Suddenly you’re jerked in your seat as the van lurches to a halt. The driver yells, “Ah, jeez. Flat tire!” You get out with the other passengers to wait while someone comes to fix it.

Everyone helps set up a tarp, and you sit in the shade while you wait. It’s taking forever for help to arrive, and you’re itching to explore the sandy landscape in front of you.

What do you do?
