To others out there: if you ever have an opportunity to crew someone for a 100 miler, it is way more fun than I ever thought possible. It helps to crew for a great guy like Jason (who I can't remember complaining once all weekend) and the sense of teamwork and accomplishment from an efficient aid station visit is a heck of a rush. I don't think this was unique to my experience, and I have the sense the same is true of volunteering at an aid station.
