This young mare was incredible.  Early morning, temperatures quickly climbing towards 100 and enough bugs to choke you with.  Her stallion was running her absolutely wild through the rough terrain and sagebrush.  Seeing them the day before with a larger band, it was clear he had lost the rest of them and was not going to loose her too.  However, she had other ideas.  She was talented and athletic, had speed and power throwing some good blows with her hind end while maintaing a fierce gallop through the intense landscape.  Once to the watering hole, he got sidetracked by a challenging stallion.  She dove in deep, swimming in some areas making her way to the middle where she filled up with nourishing water and cooling her sweat soaked body.  He actually let her rest for a bit, then dove in and the chase resumed.  That is the hardest I have ever seen a stallion run a young mare, but once the move was on, he had to work, as she was not giving in without a good fight.  When a mare is strong and powerful - she is force to be reckoned with.
