I need to make it from Ann Arbor, Michigan to L.A. in about 7 days total. Last summer I drove from L.A. to Michigan and took the southern route through Nevada, Utah, and Colorado. I'm looking to take a northern route this time through Wyoming, the Dakotas, and eventually down through Oregon and the PCH. I'm looking for advice on things to do/places to go/stay along the way. We're looking to camp out as much as possible to save money. Route suggestions greatly appreciated! We'll do anything as long as we can make it to L.A. within a week.
