There are plenty of launches to go see, including another shuttle launch in August, and if you're going this guide will come in very handy. BTW, he is absolutely correct that if you go to Kennedy Space Center you must see an IMAX movie. We're talking wall sized movies filmed in 3-D from the perspective of Astronauts. Its the closest you can get to actual space travel without getting an advanced degree in Aerospace Engineering, logging thousands of hours piloting various combat aircraft, and going through years of training where you learn to do the work of a plumber and an electrician in an extremely uncomfortable and combersome suit in an environment where the word "down" doesn't actually mean anything but the word "oops" means anything from "oops" I lost a billion dollars to "oops," everybody is dead.
Watching a lauch, btw, is highly recommended. We drove a long way, didn't get to sleep much, spent a lot of money, got screwed by our hotel, got frustrated and cranky, got rained out for two days, and spent hours baking under the summer sun, and the launch only lasts like 5 minutes. But TV cameras cannot convey how bright the engines are, how loud it is, or, ultimately, how exciting it is to see it happen first hand. When you see that machine streaking across the sky you know those guys are bad ass.
I concur there is nothing like seeing this in person even from 10 miles away. It was worth every second of time and bit of money exhausted. It was a wonderful trip with awesome friends. Nothing I can think of will be able to top this fourth of July. It was an absolutely amazing site/feeling that no words, pictures, video, etc. can ever portray. If you ever have a chance you must do this!!!
