Bison on the road are not too bad yet. Rut season usually begins in August and then park roads through Hayden and Lamar Valleys resemble LA freeways at rush hour. Except that commuters don't leave their cars, doors open, in the middle of the lane of traffic while they run out to get a photo. Enough to drive us tour drivers and other employees to tear out hair out.
Another, more recent collision killed another bison. The driver of the one-ton pick up and trailer was going over the speed limit.
