Scott, I recommend you read the guide on my website, it will tell you everything you need to know. Click on "launch viewing info." I've posted a couple of times, but I'm just trying to help out. A shuttle launch is a tremendous experience, and there are only 16 left at the most, so everyone should get to see it once.
Trust me also, it is WELL worth it to make an hour drive a few times to see it. Any questions, just ask. Good luck!
