For anyone looking for some unique roadside attractions, restaurants and historical places, I used RoadTrippers.com
for our trip to NOLA. You can plan your trip online and access it on your iPhone via their app (super glitchy, but it comes in handy).
Because of the app, we held baby alligators, saw a giant chicken in an El Camino and toured an intact plantation from the 1700s that was used in "Django". So glad we found the website!
