Castleton Recreation is starting its Youth Mountain Biking Series this Saturday at 10:00 a.m. Kids from 2nd grade up are invited to join instructor Nate Freund to learn some of the basics of mountain biking and have a ton of fun! There will be on-site registration, so all you need to bring is your bike and a helmet! We will be meeting at the pavilion next to the football stadium at CU. Hope to see you there!
