I'm starting to kick around the idea of a trip out west this summer. I've got some family in Ten Sleep, WY so that might be a destination. What's your favorite route from here (Delaware...or Philly, Baltimore, DC, etc) to there (let's say Cody, Wyoming)? I don't mind slab, I just don't like city slab. It sure doesn't need to be all two-lanes, but it would be great to avoid mega-congestion. I know there are a lot of options, but I'm asking for your favorite route. Let's assume no more than 400 miles a day and no rush to get there.
