I considered these opportunities while driving Wisconsin's driftless region  recently.
One of my routes included a return to Madison from La Crosse via Sparta and Mauston.
Sparta promotes itself as "The Bicycling Capitol of America". A museum celebrates both cycling and one of the original NASA Mercury Seven Astronauts: Deke Slayton.
Travelers needing fuel, or a charge, may find the nearby Kwik Trip useful. Beyond an impressive selection of fruits and vegetables - and road trip necessities - Kwik Trip offers a sea of gasoline and diesel fuel pumps plus a charging station of sorts complemented by a picnic table.
Just across the road, Tesla Superchargers and a dog walking area are complemented by a Culvers. Butterburgers while charging. A well stocked Carr Valley cheese outlet is a short drive away.
Detroit's Beacon Park is the most interesting charging destination I've yet seen. DTE Energy installed Detroit's first fast charging stations next to a restaurant, Lumen Detroit, light features and a concert venue.
