Chicago's Willis Tower, once the Sears Tower, is running a social media contest that links Valentine's Day with a newer tradition: Staring straight down through a glass floor from a high tower.
The Tower's observation floor, now marketed as Skydeck has been renovated with Chicago-themed exhibits and, trendily, with a series of glass boxes that stick out four feet from the building. Up to four couples who win the promotion will win a wedding or vow renewal in one of the boxes on Feb. 13, the eve of Valentine's Day. The ceremony includes 15 minutes in the box and eight guests.
To enter, couples are invited to submit a photo or video to Skydeck's Facebook page between now and January 28, sharing their love story and why they want to experience 'Love on the Ledge. Winners will be announced on Feb. 1.
