My first anecdote is a bitch, because it really scared the crap out of me - I have a not insignificant case of claustrophobia. I think it got worse after this.
It was in Boston, after I had just seen a game at Fenway Park. Trying to get into the $#(*^ subway station was one of the worst experiences of my life. The crowd wasn't mean, there weren't any fights breaking out, no one kicked or punched or anything like that. It just seemed like the entire population of Boston, let alone the baseball park, was trying to get into the station at the same time, and it did not help that the station in question (
Kenmore) was - and probably still is; this anecdote happened a year and a half ago - undergoing the construction project from hell. Anyway, I must have stood there in the midst of this seething mass of humanity for at least an hour, with absolutely no way out, until I found an elevator down into the station and thus got out of the worst of it. Although the crowd was still really bad, even after I actually got onto the train. After I got back to my hotel room, I checked myself for bruises, fully expecting to have to ice my whole body down. Then I sort of collapsed on my bed.
I'm not used to this kind of crowd, because when I go to New York, the subway stations outside Yankee Stadium and Citi Field are both *above ground* - and, unlike the one in Boston, directly across the street from the ballparks - and thus the crowd is more evenly distributed.
As for *the* worst day of my life, my worst anecdote would be three weeks after the previous one. June 27, 2008 - the storm that blew down half the trees in the city, two of which landed on my house. Actually only one actually landed on my *house*, the other landed on the power lines outside my backyard which knocked out my power for four days. My whole neighborhood looked like a warzone. It took an hour just to drive across town to check on my parents. *That* was the absolute worst day I have ever had. And I was relatively lucky that day - some people actually had their homes destroyed, and at least two people died...
