I've been riding with a local club that is similar. The group is usually larger. But there doesn't seem to be a group leader (if there is, I have no clue who it is), there's not an offical "sweep", there's no cue sheet or map. Usually, they start off and ride the first two or three miles at about 14 mph, then when they hit the first hill (mainly downhills), they're off at 20 mph for the rest of the way. On the one hand, it's great training for me. I know the area they ride in, so getting dropped isn't a problem, and it gets me riding faster than I would on my own. On the other hand, it's terrible for getting any new people in. I'm the "newbie" in a sense, yet there's been several times when I got dropped, then ran across other people that also got dropped that did NOT know the area and got to show them the way back in. (And I notice you only see these people once when that happens, go figure.) Having a "drop" ride is okay, but they should give out cue sheets or have an official sweep or both.
