I'm thinking of doing the Bun burner Iron butt ride. That is 1500 miles in 36hrs. I'll be leaving from Northern MI. Tentatively I'm thinking of heading down I-69 to I-65 down to Nashville, over to Knoxville then back up I-75 to home. Am I right in thinking that the weekend is the best time to do this? No construction, no commuter traffic. What about leaving Sat morn on Labor Day weekend. It seems that most vacationers would already be to their destination by then.
