If the Mets are going to wear a cap that isn't one of their three usual caps on September 11, they established the standard in the days after 9/11/01, for all the reasons CF stated. If I'd do anything to enhance the symbolism, I'd add a small orange Mets NY to one side or the back to illustrate solidarity -- it would explicitly state the Mets stand with the FDNY, the NYPD, the OEM, the PAPD and the other agencies the way their personnel stood with their fellow citizens in their city's darkest hour: we were all in this together and we're still all in this together. I recall Joe Torre being asked during the 2001 postseason why they weren't doing what the Mets had done during games and the MFY excuse was the MFY insignia meant so much to so many. Ack. The Mets' NY means plenty to me, but it meant plenty more that they saw themselves as a part of something bigger when circumstances away from the ballpark demanded it. The Stars & Stripes caps are a fine gesture from MLB on Memorial Day and the Fourth of July, if not always executed beautifully. They've done four iterations thus far and, in Met terms, I've found three of them incredibly unattractive. I bought the one I didn't think was too bad -- the 2010 white dome/blue bill model, to support Welcome Home Veterans. I like that MLB draws attention to this cause, though I wish they'd figure out a way to do it that didn't do a number on team identities (the Mets in red caps was an abomination). I take making each player look like he plays for the same team as a subtle message that we can't be trusted to love our country unless we all conform to one view. I see Ceetar's point in the abstract -- slopes can be slippery and, to put it mildly, I've never felt comfortable being told to stand and remove whatever cap I'm wearing for "God Bless America" (I'm all for love of country; I can do without the religious pep rally aspect) -- but in New York, a decade out, for one home game in 81 I don't think it's an abstract situation.
