Beginning with a 10 a.m. community BMX show featuring the KRUSHER Stunt Team and a bike decorating bash, families roll their foot-pedaled vehicles — bikes, skateboards, tricycles and unicycles — along a 2.5 mile course with pauses for dancing, interactive art and general zaniness. Following festivities include food vendors, bike-powered smoothies, youth games and music by local funk trio Band of the Land.
