It's April! It's spring. It's time for some fresh air. Head over to Freedom Park at 11:30 a.m. on Sat., April 6, for International Pillow Fight Day. First organized in 2008 as a part of the Urban Playground Movement, the idea is to share some public space in a noncommercial, fun, free way. Step away from the television and go hit people with soft (non-feather) pillows instead.
