When members of Battery C, 103rd Coast Artillery, under Capt. Steve J. Meade at Fort Sheridan, IIl., come face to face with a ravine that is impassable for quarter-ton “peeps,” their last thought would be to turn back or look for & way to run around it. Instead, they rig up a “sky ride” by anchoring a cable to two trees and suspending it over the big ditch. Then the peeps are slung on the cableway by means of a pulley arrangement, and a rope, powered by a winch on a truck, tows them across one at a time.
