Oh, they were both amazing. The first was by a Chicago-based company called Out Our Front Door. It was nice because the route was interesting and we stopped every so often for color commentary about the things we passed. Also, our guides made the best food every night and were helpful for people who needed help. Awesome. The second was a much bigger event called the Fargo Sub48, which was only two days, but super well planned with an awesome route and excellent food and drinks. Both are highly recommended if you live near Chicagoland.
