I love to fish the hour before sundown. I call it happy hour. I am usually alone with nature and I love it. Fish or no fish. Most times I don't want to leave at dark thirty....but have to. Are there good night vision goggles, due to today's technology, that would allow one to see a white fly line in a stream and fish after dark? Or is the military the only ones that have them. Are they available to the public at a reasonable price, and or are they as good as the military ones, or are they just junk?
