Snake Eyes
A bull snake slithers through the hands of Kenneth Grimes, 28th Civil Engineer Squadron pest management foreman, at the Pest Management Office at Ellsworth Air Force Base, S.D., Aug. 16, 2012. Bull snakes are not poisonous, but can be found in the local area and are easily mistaken for the more dangerous prairie rattlesnake, due to similar coloring and the bull snake's ability to mimic a rattlesnake's behavior.
