The fourth annual EcoFest kicked off Saturday to blue skies, cooler weather and displays dedicated to educating people about the environment or to showing off eco-friendly products.

About 2,500 people were expected to attend by the end of the day, said Keith Jones,  with EcoFest. The event included music, food, educational activities — everything from solar panels to making rag dolls — and, of course, people could see and touch.
