The phrase refers to an event, often held in the Phoenix metropolitan area, where children can interact directly with various types of vehicles. This interaction typically involves allowing children to climb on, explore, and in some cases, operate (under supervision) large trucks, emergency vehicles, construction equipment, and other specialized machinery.
Such events offer considerable value to the community. They provide children with unique, hands-on learning experiences, fostering curiosity about how things work and potentially sparking interest in related careers. Historically, these gatherings have served as community engagement initiatives, often supporting local charities or non-profit organizations through fundraising efforts and raising public awareness. They also provide an opportunity for local businesses and government agencies to showcase their services and equipment.
