I am posting a small revision to the Stockbridge-BMW route since Greg is currently off grid. There appears to be a small unpaved section on the original route in the north west corner. Greg’s track also showed using the rail trail out of Stockbridge. These areas are updated on this version. While City Nav shows Cedar lake going south from Mason Rd as unpaved, it appears to be paved on google maps, so it is unchanged.
I have also included an alternate route going back that uses Bull Run.
