Have you checked out all the spy gear available to the general public? If not you are in for a big surprise. I did a bit of research on spy gear for sale and was frankly amazed at what, up until twenty or thirty years ago was spy gear only available to intelligence agencies and the military, is on the market for sale to anyone with the cash. Items like infra-red night vision goggles and binoculars, mini surveillance cameras disguised as common house hold fixtures, eaves-dropping equipment, tracking and locating technologies, and more. This is really fascinating and also a little bit un-nerving. I say it is a bit disturbing because of the potential for misuse by unsavory people such as criminals but I can also see the practical side of using spy gear in many situations. Personally I would like to purchase the night vision goggles because I am an avid hiker, camper and hunter. Such spy gear as these would be great for when I hike well before the sun is up into remote streams and lakes for fishing and the same for hiking to my tree stands during hunting season. I cannot tell you the number of times I have had brier's, branches, unseen holes, etc smack me in the face or send me tumbling because I did not see them during the darkness. I use a flashlight but your vision is limited with it. Night vision spy gear. I like the sound of that!
