We did something similar last year, but went up to Copper harbor and back, Made a few day trip out of it. Are you intending to do this in a day, or an over night deal?
We plan to ride from Pinestump to twin lakes one day then twin lakes to copper harbor and back next day then down through porkypine mountians and back to the east 3rd day guessing 1000 -1200 miles round trip 4 days.
