Every year, in the spring and late fall the ELK call Estes Park Colorado home.
September and October mark the rut and Elk get very frisky (and dangerous) during that time.
Estes Park is at the base of Rocky Mountain National Park, which sports a motor trail through the high Rockies (open during the summer and closes when weather prevents passage).
People tend to think because the animals are in town, that they are "tame" - they are not though..
I've had numerous Elk in my front and back yard in southern Colorado, outside of Colorado Springs. One large male camped out under my back porch last year for a week (nice sunny warm spot at night apparently).. they are quite large, like horses with horns.. Not something one wants to get too close to... I do appreciate their "energy"
