As long as I've been riding in groups it's ALWAYS been used to signal debris in the road. Never a lane change.
Yup. When I was doing my almost-weekly group rides, lane changes were hand signals. Everyone can see those.
Debris on the road is a foot-point.
I always thought it was a waste of time. If you're watching where you're going you will see the debris anyhow. If you're not watching where you're going you won't see the debris or the boot of the rider in front pointing it out.
Actually, depending on how twisty the road is, the rider ahead of you can be blocking your view of the debris. Having him point it out is helpful.
Also, on roads like Mines, it can be really hard to see the sand in some of the corners. Having someone who knows what to look for point it out can help someone less familiar with the road, or less experienced, know there's an issue.
And, most importantly of all, it's courteous.
To me it means they're pitting.
^^ Pretty much this! :laughing
He dropped the leg to help maintain the balance of braking and turning that he needed to implement in order to block your pass. It's a common racetrack technique.
:rofl
You, Sir, win the internetz today! :thumbup :love
Also, aren't you past-due for some lasagna, or maybe some reasonably decent tri-tip cooked on the grill?
