Me, my wife and 3 kids will be traveling from Seattle to NY and back over 7 weeks this summer, spending one week with family in NY. To start, I have planned:
Seattle to Glacier NP
Glacier to yellowstone
Yellowstone to Mt Rushmore/Badlands
I hope to hit Chicago, Niagara Falls, Boston, Mystic and then NY, but I'm looking for things between rushmore/badlands and Chicago. Kids are 7,7, and 11.
