Finally got around to making a map of my actual tour route up to the point where I broke my seat post collar bolt.

That odd "loopage" around the Bellfonte/Bald Eagle area represents some shopping. etc., mileage I did after going to the park office to register, riding to the primitive camping area, which is miles from the park office and then heading into town for groceries, all before my rest day the next day. Odometer read 502 miles at time of bolt breakage. The discrepancy can be explained by, among other things, the mileage I put in during my day off, which included a ride back to the main part of Bald Eagle State Park for a shower and lunch down by the beach while I charged the phone and external battery.
