Getting the good kind of chills on a winter visit deep in Alaska

The train heads back toward Anchorage. The Nordic Skiing Association of Anchorage hosted the Ski Train on Saturday, March 22, 2014. About 670 passengers, 70 volunteers and 35 ski patrollers passengers boarded an Alaska Railroad train headed north from Anchorage and Wasilla to Curry, north of Talkeetna, for a chance to cross country and backcountry ski the area. But the skiing is only one attraction for many. Several parties are held on the train, and a polka band roams the train playing to a boisterous audience. The NSAA says Ski Train has been going on nearly every year for more than 40 years. (Marc Lester/Anchorage Daily News/TNS)

Bundled in the warmest clothing I own, at least I’m snug while speeding across snow-covered trails and onto the Chena River, covered with a layer of 2-foot-thick ice.
