It's 6 miles . The local trail is on the south side of m28, it dead ends in Covington. You would have to go to Covington to get 91oct eth free. That's 10 miles from Sidnaw. The mini mart in Sidnaw will eventually have 91 when they sell what they have on hand.
I donno you would have to leave that freshly groomed mid week trail and drive over bumps and stuff.
