We plan to visit Dallas this spring and would like to see the JFK sites. Am I correct in saying that The Sixth Floor Museum at Dealy and the Dealy Plaza National Historic Landmark District are where we will learn much about that horrible day in history. Would you recommend to do it on our own or a tour, we are generally independent travelers but certainly are open to a tour.While there we will also visit the Bush library and cattle sculptures.Any other recommendations for restaurants, sites, or hotels are appreciated.
