Longtime Boing Boing pal SFslim, aka Aaron Muszalski, is out in the Black Rock desert of Nevada as he is every year around this time. He's part of the crew of volunteers who prepares everything for Burning Man, from the fences to the water to the portapotties to -- spreadsheets. Lots of spreadsheets. His Instagram is fantastic. You really should follow it, especially if you think Burning Man is stupid or uncool. Seeing this phenomenon through the eyes of someone who loves it so much will melt that right into mellow.
