Two San Diego County schools are vying for an opportunity to win $25,000 worth of playground equipment.

Casitas School in Vista and Fletcher Hills Presbyterian Preschool in El Cajon are two schools currently eligible for an innovative play-set called Imagination Playground in a Box.

"It's a different way to play," said Laura Smith, principal at the Casitas School. "Instead of your typical playground you climb on, this helps you play using your brain and imagination and you can have some exercise while doing so."

Kaboom!, a non-profit organization aimed at creating more playgrounds nationwide, put on a contest featuring more than 650 schools and parks from coast to coast.

The top three vote getters will receive the playground set that features large foam blocks that children can use to build into various shapes much like larger versions of Lego's.

The blocks are housed in a large but transportable box, hence the name.

Voting ends on Friday and as of Tuesday afternoon, the El Cajon preschool was in first place.

"The kids are following this all the way through," said Robin Watson, director at Fletcher Hills Presbyterian Preschool. "They walk in my office, 'Mrs. Watson what place are we in?' It's great."

The elementary school in Vista was in third place but only by two tenths of a percentage point.

"Fourth is creeping up on us," Smith said. "So, we need a lot of help and support to get this playground of our dreams."

Casitas School is competing with a play park located in the Bay Area for the third and final playground set.
