Had half a day off today, so rather than an "expedition", I went for a "local" paddle on Gardener Lake. There is a small island, 100 yards or so from the shore, which I was surprised to learn, comprises the State's Smallest State Park. Like, less than one acre small.
That's it, folks. One trail across it, and the only development is a single "No Camping" sign, and of course, The Secret Teenage Party Firepit.
