Dropping Equestrian and elevating STUNT I'm sure shells/boats are expensive and that tranpsorting them is also expensive, but seems to me that crew is popular enough on the west coast and would add enough numbers to the Title IX formula that it would be a better sport than stunt or field hockey.
All sports involve some judgment and some physical fitness, but I prefer the ones where the winner relies more on physical attributes which can (hopefully) be measured objestively rather than sports which are so reliant on the opinion of judges. The Olympic motto is "Faster, Higher, Stronger," not "Better in the opinion of some judges."
Having said that, gymnasts are some of the most physically fit athletes around, so what do I know?
