An air field friction meter, or Bowmonk, sits in the cab of a flight line truck on Joint Base Andrews, Jan. 26, 2015. Snow removal teams use Bowmonks to test the snow and ice on the runways, allowing them to coordinate the efforts of chemical dispensers, plows and brooms. (U.S. Air Force photo/ Airman 1st Class J.D.
