When in Colorado, we lived on Cheyenne Mountain beside the old ski slope in Colorado Springs. We invaded the territory of mountain lions, bears, wild turkey, and many mice. I would catch mice in our house on a regular basis and had heard that if you let them go within a mile of where they were caught, they would come back - thus the long rides for them. I don't like mice either - they jump! - but I didn't want to kill them either.
