are you a student or professor at nc state?
take water! I usually bring a cooler and freeze a few nalgenes the night before instead of using ice because it's less of a mess to deal with. Stays cold and always good. I always bring a big ass thing of home made trailmix, because that's always helpful as well.
As far as tech is concerned, an air compressor never hurts, especially with an impact wrench, tire inflator and air gun to blow stuff off.
