I'm a frequent user of the downtown library, known as the Main Branch. I'd noticed that the homeless are frequent 'users' of that branch too, but not for what I was using the branch for.
I'd never seen a bedbug until I went to the main library one fine day about 6 months ago. And that made sense, considering the place is an absolute haven for the homeless. They have lots of comfy chairs which the homeless fill. You couldn't pay me enough money to sit in one of those chairs now.
