Noted: The Glow Float has been the nascent program’s most popular trip and has sold out the past two years. Wayfarers (which means travelers, usually by foot) paddle 6 miles from the University of Wisconsin-Madison’s Memorial Union Terrace on Lake Mendota to Picnic Point for a bonfire and a talk about the history and significance of the Lakeshore Nature Preserve (which the point is part of). On the paddle back to the Terrace, Wayfarers adorn their kayaks with lanterns and glow sticks. This year’s trip is from 6 to 9 p.m. Aug. 17 and costs $55 (includes kayak rental).
