HELENA, Mont. -- A man stranded for three days on a mountain road in Montana says he rationed beef jerky and kept his wits by playing the game "Angry Birds" on his cellphone.

David Heatherly, of Great Falls, says he took frequent naps and ran his vehicle's heater 15 minutes out of every hour until the blustery weather cleared and he could walk more than six miles for help.

The 42-year-old postal employee says he drove to the Lewis and Clark National Forest on Sunday to take photographs when his car became stuck in the snow.

Heatherly says he wrote a will at his lowest point. But when the weather cleared Wednesday, he struck out and emerged about four hours later at a home near the Gibson Reservoir northwest of Augusta.
