Loitering Sign and Alcohol

The city has posted a "No Loitering" sign on the Old Train Depot pavilion. I know during warmer weather the city does patrol the area, especially looking for people hanging around the pavilion with open containers of alcohol. Not sure how the deisgnation of the downtown area as an "entertainment district" will affect that. After all, as far as I can tell, the ordinance allows anyone within the district to wander around carrying open cups of alcohol whith no way to indicate if they got it from a local bar or brought it from elsewhere. I have seen other cities pas similar ordinances but they also created a special "outdoor" cup that the bars in the distribut would use for alcohol that patrons wanted to take off the premises. That was, other bar owners and the police would know that the berr had been purchased within the district and not brought in from elsewhere.
