Well, at least they don't on the last Sunday afternoon of January.
The regular heavy Sunday afternoon skier traffic from Summit County to the Denver area combined with extra traffic from the XGames in Aspen yesterday to create a parking lot on the two lanes of Eastbound I-70. The @ColoradoDOT twitter feed was buzzing yesterday afternoon as traffic pacing operations failed due to excessive traffic volume and traffic metering was required at the Eisenhower/Johnson Tunnels.
If you were stuck in that traffic yesterday, I feel your pain. Been there. Done that.
I spent the afternoon at Eldora Mountain Resort instead. Good times skiing with my 3-year-old boy and my 69-year-old dad (yesterday was his birthday...Happy Birthday Dad!).
