The event is a fundraiser for the United Mount Diablo Athletic Foundation. The foundation was formed to save high school sports in the Mount Diablo district.

The Bay Area Garden Society has a display at the event. Member Nancy Norris, a spokeperson for the group said "Many of us have garden railways in our backyards. What that means is that we have gardens with miniature plants, miniature bridges, little waterfalls with real water and real rocks."

The roving model was to show the model train public what they can do in their back yards and get people interested in this type of gardening.

KidFest continues today from 10am - 6pm. Click here for more information.
