Fun fact: the colored panels when Dan takes a hit from the kevlar bong (which is based on a real bong I once knew) are all from a psychedelic painting of my cat that I did a long time ago. I had it hanging in my office in the Weisman Art Museum, so I can technically say that my druggy cat painting has been hung in a museum.
Also, the campsite here is based on a real one that you used to be able to low-key use on the north shore of Lake Superior, but the Man has since put a stop to that.
