Amtrak got me in fifteen minutes early.
And I have seen the grassy knoll!
I was reading John McPhee's Annals of the Former World on the train, and it is the perfect read-on-train book, so much so that I've decided to save the rest of it to read on trains on the rest of the trip and to read something else while I'm stationary. It's about the underlying geology of the US, and the history of geology.
ConDFW this weekend, do come if you can.
