What I'd give to hit a golf ball on the moon.
Some back-of-napkin calculations, using an approximate atmospheric density of the moon of 10^-9 that of Earth, a typical CDA for a rider on the hoods of 0.40 m^2, and assuming that rider can hold 25 mph in Earth's atmosphere (leaving aside rolling resistance for this example)--with the same power output would result in a speed of approximately 403,000 kph on the Moon. Yowza!
