It’s a mad dash for the antelope when they hear or see a car coming. They feel the need to cross the road, from one pasture into another, as fast as they can. I guess it’s a fight or flight response.
Today, everybody made it across without incident. I slow down to a near stop because otherwise they get so anxious and go so fast. I just hate it when they hang a leg or scrape too hard on the barbs. There’s always plenty of time to give the right of way.
