Using Hand Signals

When we are out offroad riding we will signal with fingers how many people are behind us so oncoming riders know what is coming.
Most of the time people just look at you like they have no idea why you just held up three fingers, or give you the peace sign.
One guy got all pissed of because he thought one of our group flipped him off.:D

How many of them know that 3 stripes of lime on the ground or 3 rocks stacked on top of each other means "SLOW THE %^&K DOWN OR EAT S$%^" :rofl:
I actually saw a bicyclist signal a left hand turn yesterday, I was shocked. Of course he also ran the Stop sign :lol:
