It's only June 20th and this ride is scheduled for Oct 20th, but Keller Rd was freshly stoned as was the next available right turn Shero Rd. You can continue on Zimmerman then make a left on Rice Rd to continue route. Instead, I took a left onto Shero (very smooth fast downhill - a little narrow with bends, but awesome) which continues on to Patchin and made a left onto Boston State Rd then left onto Boston Colden.
