Nobody in particular. I just started weighing risks vs benefits of crit racing (90+ percent of USAC races around here are crits) and it just wasn't worth it to me anymore. Not that there was one specific person or team, it's just that there seemed to be at least one decent-sized crash in just about every race. It just quit being enough fun to justify the risk of messing up my hands/face and being out of work. I figured my patients wouldn't appreciate the injuries as much as my teammates.
