No Trash Pickup, Again

According to the Mayor's Office, Indy's Department of Public Works is cancelling residential trash, heavy trash and curbside recycling collection tomorrow (19 February) due to extreme cold. This cancellation applies to all DPW trash routes and all trash routes serviced by contracted trash collectors.

The City will make a determination on Thursday as to whether affected residents will have trash picked up a slide schedule or will receive double pickup next week.

This Indianapolis Observer, who has just spent a week in Quebec, Canada, wonders why "extreme cold" stops trash pickup in Indianapolis when it proceeds on schedule in the frozen North (which is much colder and snowier than Indy). What's the problem here?
