SKOWHEGAN — Police are preparing to monitor roads during the annual 10-mile yard sale in the Maine communities of Cornville and Skowhegan.

The sale, in its 31st year, sometimes brings bumper-to-bumper traffic to the area and is scheduled to take place on Saturday and Sunday. Skowhegan police say they will mobilize towing services and patrol the area for traffic violations. The event began with a handful of families and has grown in size and popularity.

The event begins at West Ridge Road in Cornville and ends at Dr. Mann and Malbons Mills roads in Skowhegan. Dozens of side roads in between also participate.

It lasts from 8 a.m. to 5 p.m. both days. Popular items for sale often included baseball cards, Army surplus clothing, and farm equipment.
