Background
Michigan's Upper Peninsula (UP) can be fairly isolated and inaccessible during the winter due to heavy snowfall and inclement weather conditions. The main transportation route between the UP and the lower peninsula is the Mackinac Bridge, which is often closed for safety reasons during the winter. Another way used to access the UP during an emergency or for search and rescue purposes is via Michigan's Civil Air Patrol (CAP), an auxiliary of the Air Force comprised of civilian volunteers.
