I live in urban Calgary, Canada...
Regardless of what's being said, Calgary is one very light polluted city.

The city of Calgary, Alberta recently retrofitted 40,000 streetlights at a cost of roughly $8 million, or roughly $200 per light. The city of Calgary is realizing $2 million per year in savings by retrofitting their streetlights – due to reduced energy costs. Calgary should recoup their initial investment in just four years.

I think Calgary did get better after this change. Still, limiting visual magnitude is 3-ish. However, with the miracle of "Stacking" I am amazed at the photos I can get.

The focus is a little sketchy in this pic - my first try with prime focus photography. No filters, just shoot and stack. 5 minutes total exposure, ISO 800, TV101.
