Mark Twain's house in West Hartford, CT

The "War Office," I think it is called, in Trumbull(?), CT where Washington, LaFayette and others met and actually plotted their course of history which brought us independence

Any of the Revolutionary War sites, esp. in New England and esp. the ones in and around Boston

Lincoln Memorial and Washington Monument, as well as the Viet Nam War Memeorial

That instrument museum wich Spaw has written about in KY, I think it is...tons and tons of trad. instruments, was it in Berea, KY?

Medicine Wheel in WY and the Hot Springs in Thermopolis, WY

Ditto on Four Corners, but travel on south and go to Acoma, also

I am sure there are others, but I cannot think of them right now
