There's camping and then there is UFO watching, Bigfoot investigating, or haunted campgrounds treks.
I thought I'd share some great things to make both the camping trip more comfortable and breezy and the investigation more effective. (links provided below photos)
I believe that the more you can see at night, the better your advantage. Using flashlights is fine for hoofing it, but when you want to know what's hiding out there, you don't want to advertise yourself with a wide swath of light, especially if what you are searching for does not like light.
Infrared "night vision" is very helpful to see without a flashlight, but thermal imaging is also a huge boon as anything putting off heat will show up and every living creature does have heat.
