KIMBERLY - The U.S. Forest Service and the Bureau of Land Management will conduct free spark arrester inspections for off-road motor-ists from 9 a.m. until 3:30 p.m. Saturday at the Rock Creek Race Track, 3618 E. 3100 N.

The inspections are part of a larger effort by the departments to educate the public about fire prevention.

The Forest Service says motorized vehicles, particularly those without spark arresters, start numerous fires each year.
