Alcohol and Preakness weekend go together like Old Bay and crabs. You don’t need one to have the other, but it sure does help. Bars, restaurants and breweries in the Baltimore area are using the 149th running of the Preakness Stakes as an opportunity to carry on old traditions (like black-eyed Susans) and create new ones (like rye flights). They hope to gin up support at a time when interest in horse racing — and boozing — is on the wane.
