I decided to look back at a ride's Flyby when the temps were above 0*F .... I rode the Loppet Fat Tire 30K a couple weeks ago, this ride has a good number of Flybys. I'm guessing competitive riders are more likely to reactivate Flybys. And frankly, the only time I find Flybys interesting are looking at a race (or once in a while somebody shouts my name when I'm out for a ride and didn't recognize them)
