I-Day has an informal PRT. It entails moving constantly in 90 degree heat, 90 percent humidity, wearing stiff whiteworks, up and down steps while hauling (sometimes pulling on wheels — West Pointers, hold the barbs) a large and heavy duffel bag, with almost no time for nourishment beyond lukewarm water in your new plastic canteen. It all ends with a ragged yet poignant march into Bancroft Hall, after which you still have a few more hours of physical movement before dropping exhausted on your rack. The fun resumes approximately 5:30 the next morning.
