Walking in downtown Frederick, vacant buildings are likely on only a few people's minds. 

People stop at the local restaurants, peruse merchandise in store windows or grab a drink at one of the bars. 

But people stop their downtown stroll at 3rd Street, where a patch of vacant storefronts discourages people from continuing down Market Street, city Alderman Ben MacShane said. 

MacShane and Frederick Uncut producer Heather Mongilio walked around downtown Frederick looking at buildings that quickly gained new tenants and those that have sat empty for a year or longer. 

During the tour, MacShane talked about a proposed ordinance that would create a registry for vacant buildings. 

Later in the episode, features reporter Kate Masters joins Mongilio to talk about the upcoming edition of 72 Hours.
