The Nam Challenge for this month continues where we left off on the north side of the area. This challenge is a great combination of speed and tech. Have fun and stay safe out there.
Starting at the Teeter Totters, head up Beaver Brook Way. Then hang a left on Milford Byway and another left on to New Trail. Break up New Trail by riding Burial By-pass backwards. Then before the end of New Trail, take Bumblebee to Adams Lot Trail and go right. Cross Holliston Highway and take a quick left on Sneaky Quickie. Then cross the Town Forest Trail to hit Optional Rocks taking a right on Town Forest Trail at the end. Finally, take a left on Tonto and finish strong to the end
