I lived in a "CRAP Hood" for 10 years. I slowly became"The Guy" to "GO to" for auto repair on the extremely cheap. Having no overhead and such. I used to listen to the gun shots at night and then the cops sirens. Never had a problem with the local hoods. They allways asked if I wanted drugs or a gun, but just told them I didn't need anything extra, thanks. I'll just fix the hoods cars. They just laffed and became customers.
