A handful of Minnesota state lawmakers joined activists for a cross-border liquor run in protest of a state law banning alcohol sales on Sundays.

State Sen. Dave Osmek was one of the lawmakers who joined liquor store owners and beer advocates in the caravan some 20 miles from the capitol in St. Paul to Hudson, Wisconsin. "I am tired of sending our tax revenue and our commerce every Sunday to Wisconsin," Osmek said, according to NBC station KARE in Minneapolis-St. Paul.

About 50 people made the trek, hoping to draw attention to legislative efforts to repeal Minnesota's so-called "blue law," which has been on the books for 80 years. Restaurants, hotels and bowling alleys are exempt from the law, because they sell for consumption on site.

Some vehicles that made the drive displayed flags depicting the state of Wisconsin saying, "Thanks, Minnesota! See you next Sunday!"
