While drug transactions can really take place anywhere in any given city... What areas in the DC Metro are considered high-crime and/or where a lot of drug buying/prostitution takes place? Specifically, I'm looking for an area where a suit-wearing, forty-ish white male would really stick out after 11 p.m. What local hotels/motels could he possibly check into to, like a somewhat run-down, possibility a "rent-by-the-hour" type?
My research so far has come up with Anacostia, Southeast, Near Northeast and areas around the Rosedale Recreation area. However, I can only find information on assaults, shootings, robberies and thefts in the area, so I'm not sure if those would be considered options. Anacostia and Southeast look very residential. The hotels I've found in the Near Northeast are chains (Travelodge, HoJo, Courtyard, etc.).
