Hand signals are nice...but if I can see you (the leader)...I will see what's behind you...I prefer people keep in control, keep their hands on the bars, and stay to the right...safety first...can't use your brake if you are doing hand signs...We do use hand signals...but there have been times in loose snow conditions where I could not take my hands off the bars...it happens...I certainly don't get mad and flip people the bird if they don't....COMMON COURTESY...goes a long way... how do you know that other sled isn't a kid, or new rider...who may know the hands signs...but isn't doing them because they are scared...or concentrating on keeping their sled on their side of the trail.....hand signs are not my pet peeve...idiots who drive with their brights on ...now that's who pisses me off!!...a guy nearly blinded me...I almost went into the pickers...cause I couldn't see...I flashed my brights on him...and he finally got the hint...I came to a complete stop..until they went by...that will get you the finger...a smack to the helmet...or ice ball from me.
