If one were to decide to go watch it at the last minute, what obstacles would one run into? Do you have to get tickets or sign up in advance or something to get close enough to actually see the Shuttle on the ground? How bad are the crowds and traffic likely to be? Does it cost a lot of money? I believe in the space program, but it's been decades since I had any noticeable space bug myself. How much would I have to suffer to see it?
On a related note, does anyone know how much I'd have to suffer to visit Kennedy Space Center if the Shuttle is safely in orbit? Whether it would be worth visiting depends on how much you can actually see on a "random tourist just walked in" tour and how bad the crowds are.
So -- does anyone have personal experience on these issues?
