Lon Strickler at Phantoms and Monsters has a good post on some weirdness caught by trail cams. Red glowing lights, strange objects, beams of light . . . and the unusual reaction of deer to those things. For Lon's post and images visit Phantoms and Monsters: Trial Cam Strangeness
The above reminded me of the strange beam of light that appeared to stop just above the ground caught on camera by Margie Alvarez in Stephenville, Texas, during the Stephenville UFO flap. (Other events came to mind, like the Skinwalker ranch, etc.)
In these cases; the ones Lon refers to, Stephenville, there is a lot of property available for "them" whoever "they" may be, to do their thing. Private property, rural, hard to get to, at night -- all good conditions for conducting covert activities.
I'm always interested in the reaction of animals to the anomalous; the animals responses are excellent clues -- and data -- in working towards figuring out what is going on.
In the beginning of things men were animals and animals men. ~ Algonquin saying
"For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much — the wheel, New York, wars and so on — whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man — for precisely the same reasons." ~ The Hitchiker's Guide to the Galaxy
