Don't bother 'aging' the carcass . Dress it out immediately as you should with any game . The off flavor is largly due to large amounts of sage brush in the typical diet. I had some caught in a wheat field - it was delicious !!
Does anyone have a "true " measure of the speed of these animals ? I had one experience where we were driving at 55 mph and a pronghorn joined us , pacing us for a mile or two. He gave no sign of effort and when bored with game he accelerated and left us in the dust !!
He must have gone 70 mph ! I've seen many numbers of their speed but no one seems to actually measured it like we did. Do any of you have a real measured max speed ??
