Where the action will be on Arbor Day.

Arbor Day (April 30) may be the Jan Brady to Earth Day's Marcia (kids, you can substitute Snooki and J-WOWW, respectively), but that's no reason to ignore another chance to help the planet.

This Saturday's Tree Spree at Northside College Prep's Joy Garden (5501 N. Kedzie) should give you ample encouragement. The free celebration includes tree planting, live music from the Bon Mots, food from Heartland Cafe, kids' activities and even a peek at the school's new $800,000 solar panel project. Head on over from noon-4 p.m.
