+1 to not drafting without permission. Heck, if I've taken a break, got a phone call, gotten dropped whatever, when I catch back up to the group I was with I will always yell "On your wheel!"

Sara, that's an example of why pacelines belong on the road and not multi-use trails. Yes, things can happen anywhere, but fast riders in a group where only one of them can see ahead, don't belong on a narrow path where the safe speed is 10 mph or less, and traffic is undisciplined, uneducated and multidirectional.

MM_, I've been riding for a long time and I didn't know there was a hand signal for tracks! Everyone I've always been with just yells "Tracks!" What is the signal???
