London, Dublin, Madison, Wisconsin, Phoenix, Tucson, Albuquerque, Philadelphia, Newark NJ, Atlanta, Memphis— off the top of my head the last few cities I have traveled to that were MUCH cleaner than Baltimore. And yes, Philly IS cleaner. Baltimore is the filthiest city I have ever lived in (and I have lived in a few mid sized cities). With the exception of LA it’s the dirtiest city I have ever been to.
