How many large cities have you lived in?  There are crazy people all over.  Denver actually seems kind of sane compared to some.

I dare you to visit Houston or Dallas or LA or NYC or Philadelphia or Las Vegas or Tampa, Atlanta or New Orleans.....or dare I say Detroit.

Camden...Youngstown....Tuscon....Chicago....Washington DC....Paris, Texas (they made a movie about that one)

And there's certainly no weird people in Austin or Portland, right?  (They even have movements to keep their cities weird).
