In the early 2000s, Baltimore and D.C. made a joint bid to host the Olympics in 2012. We were passed over by the U.S. Olympic Committee in favor of New York (which, of course, eventually lost out to London). One problem with the bid: there wasn’t enough infrastructure. We lacked in hotel rooms, transportation, and so on.
The other problem was our branding of the effort as “Washington-Baltimore 2012,” a move that Visit Baltimore CEO Tom Noonan says had bad mojo, seeing as two-city Olympic bids have always failed.
