No route fianlized yet but for the ride south... How about 83>78>377>550 (yes going right by 555, but not riding it because it kinda sucks compared to other roads in that area)>into Marietta. For the ride home out of Marietta are some of the best roads in OH (26, 255, 260, 556, etc) which ones we ride depends on how many miles you want to log that day. Going back home you can split off on 250>83 north.
