Planning a road trip this summer from Ottawa to New Orleans. Basically I want to know where NOT to stop, stay or linger on my way and there. Female going with a female and just want to be prepared. Will likely be staying in cheaper motels on the way, probably stop in Nashville for a few days. May stay in or outside Detroit if I get tired driving to Nashville as that's a 15 hour stretch. Detroit scares me some, maybe better alternative? Any chains of motels to stick with? Just safety questions really. Oh, and any must-sees along the way!
