"HOLE!" Don't be that guy
Calling out holes in a group is a good thing. But doing so without pointing is close to useless. A hand signal - even silent (but combo is ideal) - works so much better. The point, the gravel sign, move left, etc. just so much more helpful. When I hear "HOLE!" without any L/R indication, I hear "Get ready to bunnyhop" (which I avoid at all costs, that royally screws the riders behind me).
