Take it from me. If you have the following happen to you- DO NOT UNZIP YOUR TENT. Instead try to go back to sleep.
It sounds like it is pouring outside, but you are not sure.
You hear rustling outside and realize that you've left your food bag out.
You can actually hear the swarm of mosquitoes outside the tent.
You hear lots of footsteps outside in an area known to have Sasquatch sightings.
