 As for park upkeep, both union members and passing park users say it's hard to see a difference. In some popular parks around Lake Harriet, there were no overflowing trash cans or littered grounds.

The Minneapolis Pops Orchestra dropped two shows over the weekend, too, writing in a Facebook post that they rely on the workers for concert productions.
