The research has begun, but I still have a long ways to go. That said, my (quite) tentative plan is to hit the road in the days following Thanksgiving. I plan on being out on the road for 15-20 days or so. Right now the only thing holding me back is cash, but I've used that excuse many times over, and I think the time is ripe to put that concern at bay.
Here's what I'm thinking, as far as basics:
WEST TO EAST: Hwy 1 to LA -> Route 66 to the Grand Canyon, through Arizona, onto New Mexico, North Texas and Oklahoma -> drop off Route 66 and head to Memphis and Nashville -> up through Baltimore, Washington DC and New York City.
EAST TO WEST (still very unclear, but possibly): NYC -> Niagara Falls -> Pittsburgh -> Indianapolis -> Chicago -> South Dakota (Badlands) -> Wyoming (Yellowstone) -> Utah -> SF
Again, this is all very tentative, so please feel free to share your thoughts, warnings, tips, stories, etc. If I do make the trip, or even an abridged version, I will clearly post here, take photos and ask some of you for a floor to crash on.
