To celebrate the milestone, FriendsWithYou and AOL teamed up to create Rainbow City (through July 5), an interactive artistic playground filled with giant inflated sculptures and colorful characters located at the 30th Street and 10th Avenue entrance to the park. I finally popped over for a stroll after work Wednesday and it was so lovely I was still wishing I were there rather than in my cubicle today. The evening breeze as the sun set beyond the river, people watching and the children running ahead of their parents and the live band jamming away in the outdoor bar below us. All my days should end as blissfully as this.
