After skiing in Summit County on a Sunday in March, this upcoming Sunday in fact, what might the traffic be like heading back down to Denver? Any suggestion to avoid, or what time to depart to miss the traffic, or what time to wait leave to miss the crowds. What can we expect, what is recommended? Thanks. Just trying to get a heads up in advance. Fortunately, we don't have a flight to catch, but don't want to be stuck in traffic 4 hrs. either.
