The standard forecasts used throughout the transportation industry do not consider the kinds of walkable, mixed-use environments found often in city neighborhoods. As a result, the forecasts typically overestimate the amount of traffic likely to be associated with much urban development. That's a problem for proponents of urban development alternatives to suburban sprawl.
When people say Christmas is a "state of mind" this is what they mean. It's that easy-going, love-thy-neighbor, tip-more-generously, forgive-a-little-deeper, smile-for-no-reason, kind of season. That's what the spirit of Christmas is and what goes along with it is music. It's the magical combo: Christmas music + Traffic = Tolerable.
