I went out to the nasa site to try to get tickets for the launch. No such luck. They're already gone. However, there are tickets available for viewing from the Astronauts Hall of Fame, which is right outside the space center.
Then I started thinking about it.
3:45pm on a holiday weekend in July and temps around 95 with 95% humidity and decided that the best place to watch the launch might be either from in a pool at disney or on TV.
I didn't even consider having to leave at 8am because of crowds. (thanks flysway2much).
