So I am planning a road trip to do with friends once the COVID-19 situation is all over. We plan on camping besides in Denver and Chicago. We don't mind driving long distances if it means we will be somewhere we will be somewhere cool the next day (besides days 1 and 2 we want to power through to Badlands NP). We will be leaving from the Allentown area in PA, and my rough itinerary is as follows. I wanted to know if you guys think this is doable.
