From the Rocky Mountain News, 1884 a prominent Denver hotel keeper speaks.
"What is to become of the city if bunko men are to be allowed the swing they have now?
We have had over a dozen guests of our hotel bunkoed in the fortnight and travel is actually falling off on account of it. People are getting afraid to come to Denver.... There are about a dozen bunko sharks hanging around this hotel all the time, and by the time a guest gets in he is either robbed or talked to death."
