It's that time of year - the elk are bugling. I had a beautiful 7+7 bull elk at it all night outside my window. He might have gotten some - at one point he sounded like Forrest Gump imitating the noise his Mama and her lover made. Sure hope he finds his harem soon, though.
In addition to it being an incredible thing to hear at night it can be a little dangerous. Elk are not going to attack or mistake you for a female but the boys do get a little stupid when following the girls. They'll cross the road without looking both ways and can pose some problems.
Sooooo, if you're coming to Colorado be certain to watch for wildlife and brake for animals.
