I was on the express bus on the way home from Manhattan last night listening to the Yankee game on the radio when the reception went out for a few minutes. Wouldn't you know it? That was literally the exact time that Alex Rodriguez was hitting No. 660! So I totally missed hearing it live! Bummer.
When I got home, I did get to see the TV clip in the postgame of A-Rod hitting it, then I stayed up late to watch the rebroadcast of the game to see the homer in context. Just seeing a clip of the homer itself really doesn't do the event justice.
