Are there any neighborhoods or streets in Boulder that are really decorated for Christmas?

As you might expect, Pearl Street is amazingly beautiful for the holidays. What you might not know about is the Festival of Trees. Many of the shops lining Pearl Street are displaying some gorgeous and unique trees that shoppers can pay $5 for a chance to win. The profits from this event will go towards a charity, so it is also supporting a great cause! Check it out before Dec. 18th as that is the day the winners will be announced.
You can see pictures of the trees at this site: http://www.boulderdowntown.com/events/lightuptheholidays/festival-of-trees/photo-gallery.

Happy Holidays!
