An after-Thanksgiving marathon one year when what would normally be a 3 1/2 hour drive from Denver to Gunnison took 13 1/2 hours, including a leisurely 15 mph or less drive through a blinding blizzard in South Park, and a 4 1/2 hour wait at Garfield (on the eastern side of Monarch Pass) waiting for no less than 4 jacknifed and wrecked semis to be cleaned up about 5 miles up the road.
