A rough plan is in place.

Fort Wayne to Madison.
Madison to the Badlands.
Badlands to Mt. Rushmore.
Mt. Rushmore to Yellowstone.
Yellowstone to Seattle.
Seattle to Mt. St. Helen's.
Mt. St. Helen's to Portland.
Portland to Eugene (couch/floor).
Eugene to Redwoods.
Redwoods to San Francisco (couch/floor).
San Francisco to Yosemite.
Yosemite to Sequoias.
Sequoias to Death Valley.
Death Valley to Las Vegas.
Las Vegas to Zion.
Zion to Los Angeles (couch/floor).
Los Angeles to San Diego.
San Diego to Tijuana.
Tijuana to Mesa/Tempe. (couch/floor).
Mesa/Tempe to Grand Canyon.
Grand Canyon to Roswell.
Roswell to San Antonio.
San Antonio to Austin.
Austin to Houston (couch/floor).
Houston to New Orleans.

New Orleans is a turning point. We can either go to Mammoth Cave or the Everglades in Florida, depending on how we feel at that point. We're leaning towards Mammoth Cave.

New Orleans to Mammoth Cave.

Mammoth Cave is also a turning point. We could go home or to Bar Harbor, Maine/Nova Scotia. I'm leaning towards Nova Scotia but Deanna is leaning towards home. Mostly, I'm thinking it'd be neat if we could say that we were in both Tijuana and Nova Scotia two weeks apart because they are two complete opposite corners of the continental US. We will have been on the road for a month at that point, so we may both feel like just going home when the time comes. All the same, if some kind of miracle occurs...

Mammoth Cave to Brattleboro/Burlington, VT (bed/floor).
Brattleboro/Burlington to Nova Scotia.
Nova Scotia to Niagara Falls.
Niagara Falls to Fort Wayne (home).

Potentially 32 days at asphalt.
About $1,000 in gasoline.
A food budget of about $200 each.
