It may well have been more than 3 hours, but it was ugly.
I do have a plastic cue sheet holder that velcros around my bar. Not part of a handlebar bag. When I lead AMC rides, we are required to give out the sheets (although we provide a link to download to GPS, it's not required). Some people use a clothespin to hold it (?), and others just follow. We are required to keep people together, with no one left behind. That's why we screen. However, when we do the 2 annual rides we lead, it's show and go. Some of the people should not go, if you know what I mean. The cue sheet is important here; these people are not going to be using a Garmin. For a charity ride, obviously, that's not going to happen. I print my sheets in a larger font, front/back if necessary. I *never* look at the maps that have been provided on some of the rides I've done, as you can't really see anything.
