It what has become something of a Blogtown tradition, I've got two copies of the 2012 Dead Memories Portland calendar to give away. The calendar collects images from Portland's past, and they make great Christmas presents for anyone in your life who has lived in Portland for a while. (The group's Facebook page—where users have submitted a ton of pictures—is also fun to browse.)
Email me by 10 am tomorrow with "Dead Memories" in the subject for a chance to win. Caveat: You have to be able to swing by the office tomorrow to pick it up if you win. If that timeframe doesn't work for you, the calendars are also available at Powells' Burnside, Hawthorne, and Beaverton/Cedar Hills locations.
