my first ever dh bike will be built tomorrow, and i'm dying to ride it. as a 16 yr old kid, it was hard for me, but after 7 months i managed to by a bunch of used parts and an old frame. but i'm dumb. i know there are a bunch of trails around but i don't know how to get to any of them. i need an easy trail near boulder for me to ride this weekend. i like that stuff up the canyon northwest of boulder, any good trails for me to get my bairings on up there?
