When I was in elementary school, field day consisted of gathering pledges from soft-hearted relatives and then running laps around the square patch of grass on the playground. I remember a grape popsicle afterwards.
Here in Durango, Maggie’s school has taken a different approach. During the week, you earn a raffle ticket for each day you walk or ride your bike to school. Then on Friday there’s a big celebration with bike obstacle courses, raffle drawings (cool things like lunch boxes and tennis shoes, but also bikes!), and a bike parade where everybody gets to ride through the school halls and around the neighborhood. It was (barely) maintained chaos, and so much fun!

That looks wonderful!
