Photo Finish
Cool
photo finish from today's Tour stage... If you consider center of
gravity, Sagan (bottom) probably got his over the line first, and his
helmet definitely beat Greipel's. Sagan is also moving faster as he
crosses the line. It's the leading edge of the front tire that matters,
though, and Greipel's textbook bike throw wins the day.
For my
non-racing friends, the photo-finish camera is only looking through a
thin vertical slit at the finish line itself, so the horizontal
direction in the photo actually represents time. That's why the wheel
spokes look so odd. It's also why I say Sagan is moving faster... He spent less time (horizontal distance in photo) in view of the camera.

Crotchety
Happy to get a 50-mile ride in today, but three (three!) bike-related pet peeves reared their heads.
- Cyclists wearing earphones. Why do I bother calling "on your left"? You're oblivious. This is an epidemic that's going to get people killed (and it's illegal to boot).
- Unfriendly riders. Pull up next to a guy at a red light, say, "Morning! How's it going?" and NOTHING in reply (and he's not even wearing earphones). I'm not looking for a riding partner, I'm just saying hi, dammit. We're both riders fighting the elements and traffic. How about an iota of solidarity?
- Wheelsuckers who don't introduce themselves. Look, all I ask is that you come up alongside, say, "Hi! My name's Fred. I'm really tired; do you mind if I sit on for a bit?" before engaging the tractor beam for miles. That way, I know you're there, and I can say, "Fine, you can sit on, but I'm not going to point out hazards for you, so be careful." If I'm riding by myself, it's because I want to, but I'm not going to hook you if I know you're there.
