"point out hazards".... only if you feel comfortable doing so. If you know you'll swerve even just a bit when lifting one hand from the handlebar, don't do it, because you'd be creating a bigger hazard.

Otherwise call them out.

Potholes do not necessarily need to be called out, unless the pack is going at a very very high speed.... Glass, metal objects, sand, etc. should be.


Signal stopping or call "STOPPING". In a big group, it is useful to signal by raising your arm vertically with an open palm instead of keeping it low, in your back, so people far behind will get the signal too.


When there are a few cars parked on the right-hand side of the road, DO NOT change your line to get closer to the curb/sidewalk when there are no cars. Just hold your line, as if you always had cars parked to the side, until you get to an area with no cars at all. (Cars coming from behind won't see you if you keep swerving between parked cars.)


Do not look at the person's wheel, but through her hips. Staring at the wheel will make you micro-correct your trajectory and in the end swerving all over the place.


Stay focused but enjoyed the ride.
