Two bus loads arrived with one mission: to make a difference in the place where students learn. Volunteers grabbed a bucket of paint, a few brushes, and they set off to help Chicago Public School buildings.

This year's 16th annual Chicago Cares Serve-a-Thon brought volunteers to Chavez School on the Southwest Side to Chicago International Charter School on the North Side and 39 additional schools in between.

Volunteers from WGN News and Tribune Media Group were working hard to spruce up the schools for students. The day started with a rally at grant park, but the rain not dampen their spirits.
