How is it working at Boulder's Pearl Street Mall? It was crowded when I was last there.

This isn't about the bums, it's about smokers. No one has to smoke. They chose to. There is no downside to a smoking ban (the vaping ban seems excessive). No visitors will avoid the mall because smoking isn't allowed. The problem is that Denver's keystone kops can't/won't enforce it. Heck, where I live they can't even keep bikes off the sidewalk.
