Sunday, drive across bridge (an experience in itself) to St Ignace. Perhaps the newly-licensed teen will get to do the honors.
Camp out with a bicycle tour of my acquaintance. No campfires, no picnic tables, just a bunch of tents and bikes at the high school.
Walk bridge to Mack City. Crawl to ferry dock. Ride boat to Island.
If my sis doesn't bail out, I plan to bring my unique Counterpoint tandem for her to ride on the front. I've even figured out how to get it to the island (and not be joy-ridden? joy-rode? borrowed) and waiting for us once we get there.
