The search and rescue team was composed of two Toyota Landcruisers and one Jeep Wrangler. During the next few hours we came to the conclusion, as did the crew chief, that the driver of the second Landcruiser was a liability to the mission. I will not go into the details, but an inadequate knowledge of his truck, tools, and tool usage nearly ended in catastrophe. The crew chief and I were able to help the ill-equipped search and rescue team member (this should be an oxy moron) get off the trail safely.
