If you can get a slot at the LC39 Gantry, tickets for which cost $50 in addition to KSC Visitor Center admission, that'll definitely be the place to be.......
Perhaps we could come up with a NSF 'recommended places to watch from' list of locations - and known 'gotchas' - cant park here, no public access there, KSC Visitors Center closed at night.... I have a vested interest as I'm going to be around KSC around the launch window, so am looking for suggestions Paul
