The only thing that sucks about going to the mountains for the weekend is coming home in Sunday-night traffic. Giant SUVs struggle along like lumbering mammoths, and at the slightest trace of snow or ice, traffic often snarls to a halt. Frustration sets in fast: People want to be out of their cars, into their homes. A small ray of hope appears just pass the turnoff for Golden, where a third lane opens on the left side of eastbound I-70, giving savvy drivers a chance to pick up speed. It's an uphill stretch, but anyone who anticipates the break and has enough horsepower under the hood can stomp on the gas pedal and leave at least a dozen grommit cars behind. You may not go as fast as you did on the slopes, but it'll feel like you're flying.
