Although The Crew is very much a social, online game, it doesn't appear to have the same contests or events as Need for Speed World did. However, this could change or it already does and I just haven't found that information yet.
In any case, during an earlier exploration of the map offered ingame, I came across a town on the East Coast that seems to be stuck in Halloween year round. Tonight, I spent some time retracing my steps to present the following video, a self guided tour of Salem (just look for Salem Woods on the map, northeast from New York).
Filmed from late dusk and into the night really was merely a fantastic coincidence.
