How do you mean exactly? There's police around, but I'm not going around meeting people on the street. It's pre-arranged with a cell phone and I'm usually in the vicinity of Southern or maybe Yale, so being white isn't an issue. I'm never really going to any bad areas. The pharmacy where I get rigs is sort of at the start of a rougher area, but aside from people asking for change or a spare rig if they see me buying a ten pack, I never really got hassled. (Knock on wood)
I have copped on the street. Would not suggest this. It was a few years ago and even though I did meet a connect and a middle-man (well older black woman, she was pretty cool actually), I got ripped off at least twice and it was pretty shady. I did meet this cool black girl one night who helped me cop. I thought she was selling, she thought I was coming to fuck a black prostitute (she was a crack whore - literally), a hilarious mix-up, but I ended up with bags and she got some money for crack so it was all good.
Not to be racist as my dealer was black and he was cool as hell, but if you meet someone off the street and you're white and look not homeless they might try to tell you an inflated price per bag.
