Expectation: everything is packed, settled, and working exactly as planned.
Reality: the trailhead huddle has other ideas. Trail decisions are safer when vehicle limits, recovery access, communication, and environmental impact are considered before momentum.
A little patience, a quick check to stop and inspect before committing the vehicle, and a willingness to laugh at the timing usually restore order. The story gets better once the problem is behind you.
Taking a quick look before committing can save a lot of trouble later.
