The Rave Run Shakopee, Washington

As night falls, participants in the noncompetitive Rave Run pull on neon T-shirts, don glow-in-the dark glasses, and stuff their pockets with glow sticks. Spectators look on as the throng of illuminated runners, which includes kids and adults, make their way through a 5-kilometer course that winds through city streets.

The event culminates with an after party, where a DJ spin tunes and powerful lasers cast out beams that illuminate wide smiles and the secret locations of any lost arks in the vicinity. Fog machines and CO2 jets help create a high-adrenaline atmosphere as attendees dance with their glow-in-the-dark compatriots. All the fun is for a good cause; The Rave Run partners with a local charity in each participating city.
