More than 100 pre-schoolers hopped on their bikes and tricycles today to raise money for a good cause. Children from the New York Institute for Special Education took turns racing around the building for the 10th annual Bike-A-Thon. The goal was to raise money for St. Jude's Children Hospital while demonstrating all the skills they've learned at school. Both teachers and parents sponsored the pre-schoolers. Last year, they raised nearly $1,000.
