Recommended rest zones: the Michigan Welcome Center (mile marker 1 on I-94), the Lake Forest Rest Area (near Oconomowoc, WI), and the De Pere Rest Area (near Green Bay). For off-route hidden gems, detour to the New Glarus Brewing Company (New Glarus, WI) for a taste of Swiss heritage, or visit the House on the Rock near Spring Green, WI.

Infrastructure safety: the route has good cell coverage (AT&T and Verizon), 24/7 gas stations every 30 miles, and ample diners for quick meals.

In Milwaukee, stop for cheese curds and bratwurst at the Milwaukee Public Market. Green Bay offers iconic fish boils at places like the White Dog.
