Probably were the sort of unsavory types that might, hypothetically, take a group out to the middle of nowhere, stop, check the map, announce "OK... we missed a turn, we're going down to that last road we passed" and "accidentally" drop one of the riders. :-)

Calling the cops on your own members is harsh... I think the Team Cinzano approach is more appropriate amongst "friends."

And, yes, I'll be checking to see if you have a frame pump next time I ride with you...
