While technically two cities, Dallas and Fort Worth share one major airport and are only a 40-minute drive apart (and Ubers are very cheap here). I highly recommend spending at least a day or two in both, so you can see just how different they are. In Dallas, I started my day by venturing to the top of the Reunion Tower where you can take in a 360-degree view of the city, including a bird’s eye view of the streets where John F Kennedy was shot.
In fact, the Texas School Book Depository where Lee Harvey Oswald allegedly shot the president has since been turned into the Sixth Floor Museum. At first I thought it may be a bit too morbid for me but I actually found it really fascinating, with an audio tour shedding light not just on the event, but JFK's entire presidency, and the conspiracies following the shooting.
