In addition to this,,,,, and I know how easily things are forgotten,,, after a stop, light or sign or whatever, keep your speed down to below 30mph, so that everybody can get together. It's great to have somebody at the rear, a tail gunner, to tell you when all out, so that you don't take off too early. If you don't do this and you've set your max speed at 50 mph, the last person in the pack will often hit speeds of 80mph just to catch up and keep the group together,,, and it is important to keep the group together and smaller, as Brad said 10-12. Here again, if it's too large the group will spread out too far and some cager will get too impatient and cut in between, or try to pass, can't make it and cut into the group without a second thought about a rider they are cutting off.
