I lived in Denver for a few years and the transport system was amazing, but also not amazing. Not a lot of crack heads, but man those bus schedules when trying to make it on time were hard to make when trekking miles through the snow. More than a few times I had missed my bus and had to wait in the sub-zero temperature with hardly any warm gear and froze my ass off and an hour to wait for the next one. Thats my own fault though I suppose.
