A little bit whimsical and a lot of green and artistic, PARK(ing) Day encourages urban creativity on a small scale. Throughout the day on Friday, Sept. 18, over 50 mini parks, or "parklets" will pop up at various locations in the city from 8 a.m. to 5 p.m. Transforming metered parking spaces, the parklets will encompass 170 square feet and will be designed by local artists, activists, planners, business owners and more.

Out of the dozens of creatively designed spaces, here are a few not to miss.
