Haha, sorry, shooting gallery is, admittedly old, slang for an area where people do drugs without consequence. Comes from when heroin was the big scourge.

In Vancouver, Hastings is a super sketchy area that breaks your heart to see (and sometimes, your bones. An elderly friend is in one of the social housing projects there and was hospitalized awhile ago after some asshole shoved her to the ground and stole her purse.) But it is also right next to one of the nicer touristy kind of areas so you'll occasionally see very bewildered tourists or young folk new to the city terrified and out of place.
