Some comments about this we saw on the web:

* /u/StickyNiki on /r/BurningMan This foil ducting stuff. When a huge RV parked next to our shade structure, their exhaust was pretty much dumping into our camp. We slid this over the tailpipe and directed the exhaust away from everyone. http://www.amazon.com/gp/aw/d/B00WW5HRGG?psc=1
