Sleepmonsters - they are real

I followed team Untamed Adventure Racing to the finish line on day 5 of Expedition Africa 2015. They had about 3 hours of sleep in total in this 5 days and it became visible when the sun went down.
I know of these "sleepmonsters" but it was great to be able to capture it. I only caught part of the conversation but you get the idea. :-)
