Sorry to drag up an old thread. But seeing your quote I thought I would pass along that you might be one of the people responsible for beating on my DS (inderectly) recently at CST tryouts.
He didn't want to give too much away, but he did share that the PT portion was the single toughest thing he'd ever been through physically. If you knew his flair for understatement, that's saying something!
I guess they got back near midnight after having run to and from Jack's Valley (what? 6.6 miles each way at altitude!) and a whooooole lot of stuff in between. He and his squadmate were totally exhausted, covered in dirt, etc but so pumped on adrenaline that I guess they "attacked" the rest of their roommates when they got back (no furniture broken that they reported!).
In any case, he's made the probaitionary team and I'm not sure I've seen him prouder!
