Hi all.
This being the 5 time in USA I have been a lot of places. But never done a road trip on the east side of USA, only West side.
I´ll link the picture of the road we are planing to drive.
Would be nice to get som hint on what to see and do close to this route. or if we should drive a bit different to se as much as we can
The trip will be 4 weeks, starting in NY ending up in Miami
tanx for any comments
have a nice day 
Greetings from Norway
This will be a great trip - depending on what time of year you go, you could pass through several different climates!
I am from the Chicago area, so I am partial to that city. If you haven't been to the Art Institute of Chicago and you are interested in that kind of thing, you should really check it out. It is one of my favorite art museums in the world. It is also located right next to Millennium Park.
Springfield, Illinois has some interesting spots, namely a lot of Abraham Lincoln sites-his tomb, family home, etc. Could be a nice little break on the drive that day.
Sadly, I have never been to New Orleans but it seems like an amazing city, culturally and historically. Finally, if you're looking for something a little amusement-park-ish, consider jogging south on the route between New York and Chicago to stop in Hershey, Pennsylvania. Kind of an Americana experience.
Good Luck!
If you're interested in seeing what may be a less glamorous but more (maybe) typical side of the u.s, i'd recommend stopping in Cleveland. Cleveland is a typical rust bowl (former center of industry and manufacturing) city and although it is home to the worst national sports teams in the history of civilization (which is something we're dearly proud of), brutal winters and scorching summers, and some of the most polluted bodies of water in the U.S, it's also home to the rock and roll hall of fame, The Great Lakes Brewery (which is definitely worth a visit if you like beer), the west side market (which has been operating since around 1840), and a myriad of other places.
Cleveland isn't a New York or Chicago, but it is filled with good, working class people who have refused to leave, despite having no reason to stay. if you want to see a more down to earth and "regular" part of the country and you have two or three days, i recommend cleveland.
hope this helps
P.S- if you want to see even more down to earth people, i recommend Holmes County, Ohio. It's about two hours south of Cleveland and is home to the largest community of Amish on earth. "Amish country" makes for a good day trip.
Also
Florida Everglades, if you like nature at all, you will love the everglades.
Also, also
When in New Orleans, make sure you eat some Crawfish and jambalaya
In Orlando, go to all the Disney and Universal Studios amusement parks, such as the Magic Kingdom, EPCOT, Animal Kingdom, etc. In New Orleans, make sure to visit Bourbon Street and some of the plantations alongside the Mississippi River. In Memphis, visit Graceland (Elvis Presley's old home, which is south of town), and also visit Beale Street and get some barbecue and also see BB King's Blues Spot. The old Sun Recording studio (also near Beale Street) is where Elvis first started recording his records.
In St. Louis, visit the Jefferson Arch--including riding the elevator to the top. In Chicago, if you come when it is warm, visit the area down near the Chicago Cubs baseball stadium (called Wrigley Field)--and take in a day game if you can. It's a real fun area with lots of young people in the clubs and restaurants. When passing through South Bend, Indiana (just a ways east of Chicago), visit the College Football Hall of Fame. In Cleveland, be sure to see the Rock and Roll Hall of Fame. Seems like it should be a great trip.
