SCOTTSBLUFF, Neb. (AP) — The state’s tourism commission has selected two sites in western Nebraska to benefit from a new volunteer program.

The commission’s selection committee chose the Robidoux Trading Post near Gering and the Cowboy Trail near Chadron as the inaugural sites for the program, which will help maintain or improve sites that are popular with visitors.

Volunteers will help restore the historic trading post on May 6 and 7 by removing the chinking, an old form of weather-stripping material stuck between wooden boards to help keep structures watertight. They’ll replace it with a longer-lasting material.

On June 10 and 11, volunteers will clear old railroad ties on the Cowboy Trail, build simple bridges and do other tasks to prepare the first five miles east of Chadron for further development.
