TribLocal Community Photo challenge: Happy holidays Shedd Aquarium TribLocal is looking for photos that best represent the holiday season. We want to see your Christmas trees, decorated homes, holiday parties and other festive snaps that evoke the spirit of the season. Each week from Dec. 17 to Jan. 20, we'll choose one contributor's photo that best represents the holiday theme. That contributor will win a four-pack of tickets to the Shedd Aquarium.
