UPS spokesman Mark Dickens says parking tickets are a cost of doing business in some cities.
The newspaper says parking tickets are on the upswing in Denver and are on pace to hit 670,000.
That would be 14 percent higher than last year and the most since Mayor John Hickenlooper took office in 2003 after making parking tickets a campaign issue.
City officials say they're not trying to drive up revenue. They say the increase is caused by more residential parking zones, more parking agents, replacement of faded no-parking signs and population growth.
