I managed to watch it roughly 15 miles from the pad in Cape Canaveral, although it disappeared after only a few seconds (s****d cloud cover </3) and I didn't get any in-focus pictures.
Honestly, I think the banquet I went to afterwards was the most interesting. 2 NASA employees (Who were part of the investigation with the RCC panels after STS-107) gave an hour presentation, and I got to hold and inspect an RCC T-seal that flew on Discovery 33(ish) times.
