Account

Five people camped in a remote forest-swamp area to look for sasquatch. After they went to sleep in their tents, they were awakened a little after 4 a.m. by a very loud long yell lasting about 10 seconds from roughly 50 yards away, with coyote yelps and several shorter yells mixed in. After the sounds stopped the woods went completely silent.
