I remember laughing out loud at the scene in the movide "Indiana Jones and The Raiders of The Lost Ark" when Indiana escapes Hovitos tribe and jumps into his pilot's plane only to find the flyer's pet snake, "Reggie."
Jones screams, "I hate snakes, Jock! I Hate 'em!"
That's me ... I hate them and, after all, Satan was a serpent, a snake, slithering around on his loathsome belly. Secondly, I lived in Arizona and have seen more than my fair share of rattlesnakes on mountains I hiked and on and around golf courses I played.
Anyway, this live web cam was set up in northern Colorado and it is believed that more than 2,000 Prarie rattlesnakes live in this one singular den. So, if you are interested in such a thing, you have found your viewing paradise.
BTW: If you look in after sunset or before sunrise it will be grayscale due to the infrared camera. No lights are used to keep the den's "residents" acting normally. (I want to know who had the courage to set that web cam up?)
