I don't want sources, nor do I want people telling me not to do this. I went down to a couple of supposed hot spots today dressed like a junky and trolled around looking for some gear. I've never had to do this before. I don't want to get stabbed or fucked over. Just looking for some advice. What's the best approach? Do you go up to people and ask them? If so, what people? How do you ask them? Are train stations good places to try or is that a myth? I'm going to find some anyway, so just help me do it safe if you can. Thanks.
