Pronghorn Antelope Graduates of The Prometheus School of Running Away From Things

"Well, then run TO THE SIDE!" Only got 33 mph or so out of this pair, a cool half of their speed potential. No need to unduly stress them by being a dick, despite almost ASKING for a chase race. However I did respect the first pronghorn -- too far in dash cam POV to be clear but liked how it stood its ground in the middle of the road as I approached, clearly waiting for his/her companion instead of instantly fleeing and leaving buddy to their fate ... like every other animal it seems, even the cows!

Both sexes have horns; females smaller. This pair seems to have contrasting sizes so perhaps a mating pair?
