I just saw this article on the top 10 destinations for history buffs. I've did my history road trip to each destination except Montogomery, Alabama.
My favorite travel destinations are probably Boston and Philadelphia. You can go to each city in the morning and spend your whole day just walking through the city just seeing historical sites all day. Most of the historical sites are located close together also. I like Gettysburg except its getting a little too commercialized.
