I haven't been to the present home of the Yankees (a fake phony fraud counterfeit artificial stadium without a soul that was built on parkland stolen from the neighborhood, and run by an organization that needlessly turns a simple request into a free speech issue ["Ticket holders acknowledge and agree that the Yankees' ban on foul/abusive language and obscene/indecent clothing does not violate their right to free speech"]) in a couple of years.
But in 2009 - and I have no reason not to presume it's still there today - there was a sign at the entrance to the Steiner Team Store asking people not to take pictures inside.

What have they got to hide?
