What Is The Most Dangerous Creature You’ve Seen Near Grand Junction? (POLL)

With the report of bears near Fruita, I'm wondering what is the most dangerous creature you've encountered here or near the Grand Valley? My first guess would be bears, but I've been told more than once that the animal you really don't want to surprise is a moose. Bullwinkle cartoons will just not be the same for me anymore.

I've also read that scorpions are fairly common around here although I have yet to see one. The only Scorpions my wife is willing to hear about also sing "Rock You Like A Hurricane".

Have you had any brushes with dangerous animals and/or creatures? Please share if you have a cool story!
