One thing I'll miss about Paris is wandering through the banlieus and watching kids doing parkour <http://en.wikipedia.org/wiki/Parkour> , the French-invented style of street stunts that requires no sporting equipment except buildings and balls. Reindeer are so passé...this is how Saint Nick makes his rounds these days.
