My colleague and I both needed to return to Ohio by late afternoon so we made an early start from the resort. When we arrived the ferry was loading and almost full. We were lucky to be the last vehicle on the water being waved by a bigger sport ute.
I liked Drummond Island. If time weren't in short supply, I would gladly return for a couple days with Ali so we could explore together (and clean out the remaining caches on the island). I like the area between Drummond Island and Mackinac even more. There was a lot of quiet, peaceful shoreline between the two.
