Curb Crawlers in Gowanus

where were the tennis courts at? In the empty lot?

You should be careful walking around there by yourself at night! Gowanus is known (at least in my experience) to have prostitution and drugs. Hell I've been offered sex by probable crack addicts. I once found a big baggy of what I think was crack. Just because you were wearing sweat pants doesn't mean someone would think you weren't a prostitute. Prostitutes don't only wear stereotypical hooker garb like high heels and shorts skirts.
