Kids, you really don't want to do this: Spend two weeks' collecting old CharlieTickets, then have a ticket-redemption flash mob at Downtown Crossing. It's one thing for Ron Newman to do it; quite another for a whole gaggle of 20somethings to tempt the T fates:
... We will line up and wreck havoc. We might even trash the place in rock star fashion! ...
No, you will all get hauled off to whatever passes for a T jail as some stern T cop warns the assembled media about the imminent arrival of mayhem in the streets. Just ask those graffiti taggers from Germany and Wisconsin.
