Karla Owens knows a little bit about Rodney Dangerfield, now delivering punch lines inside the pearly gates and who always started his gigs with, "Ya know, can't get no respect!" Owens, the Mainstreets manager of the Bloomfield Business Association, receives personal kudos for her hard work. But she fights every day to get Bloomfield the respect it deserves. And these days, it is tough to keep city neighborhoods vibrant, attractive and safe. Ignorance? Corporate disdain for local customs? Going for snob appeal? If the city were a homogeneous urban blob, there would be no reason to spend time here.
