In 2005, 30 shops signed up to participate in the 2005 Best Helmet Fest, a public-spirited, helmet-decorating competition among stores in the Cherry Creek area to benefit the Share A Cycle project, which refurbishes used bicycles for children in need.

Check out the helmets in the Best Helmet Fest 2005 Photo Gallery.
