Objectives:
Clinch only segments of I-94 I'm missing (Minneapolis-St. Cloud, Port Huron-St Clair Shores)
Clinch segment of I-75 I'm missing north of Knoxville, TN (Sault Ste Marie-Birch Run)
Clinch 3di (380, 535, 675, 475, 696, 275, 280)
Clinch several counties in IA, MN, WI, and MI, including all I'm missing in Michigan UP (Gogebic, Ontonagon, Houghton, Keweenau, Baraga, Iron, Dickinson, Marquette, Alger, Luce, Chippewa)
I generally do these trips solo, but if this sounds interesting to anybody, I wouldn't mind a companion. Approx 10-11 hours each day in the car. Would need passport.
