So what's the idea behind Community Vacation Bible School?

Well, Community VBS began in 2005 as a cooperative effort between 4 of the local churches that participate in CUIC, Churches United In Christ.  Those churches are:

Cerro Gordo United Methodist Church

Cerro Gordo Church of the Brethren

Cerro Gordo Brethren Church

Oakley Brick Church of the Brethren
