I'm going with two or three of my friends this summer to the Dallas area to pick up a friend who will be coming back with us. We will be starting out around Indianapolis. We'd like advice about what we should stop to see along the way. We don't need to go on an extremely direct route if there are attractions a bit out of the way worth seeing. We're young, and not sure what types of things are on the way to Texas. We just want to have some fun!
