Hi - Boulder Bend trail is nearly 100% used by bike/ped and is a major part of the local trail network. Ok if I change to highway=cycleway,  foot=designated, bicycle=designated, motor_vehicle=private to account for the (very rare) maintenance vehicle?

https://wiki.openstreetmap.org/wiki/Tag:highway=track
has a note about situations similar to this, "For an old road that is now only used by pedestrians, bicycles, and/or horses, highway=path may be a better choice." (though I think cycleway makes more sense than path in this case)
