IMO, a city with 20,000 people would have crime more like what we're talking about than a city with just 2,000. A smaller town would have less opportunities and more internetworked personal connections which would affect how a criminal or a drug addict could survive outside the mainstream.
Anyway, last night's episode was... quite a thing. I liked some of it, but some of it felt like when you were a kid and you'd get all your GI Joes, Star Wars, Transformers, and He-Man figures together and just smash them into each other. And once again, not enough Raylan, not enough Art, and Tim & whatsherface can't seem to carry a storyline on their own.
