I have to say that the best group riding I have ever been in was the GA Rally. Chy was so organized and clear on everything, everyone was spaced so well with no rubber-bands, the whole thing changed my ideas of group riding. This is what a group ride should be like; I really enjoyed it, way more than other rides I have been on.
Until the GA Rally, all I had done was the local rat rides. Loosely organized, riders all over the place, turns (intersections) coming up with too much speed and some last-minute breaking into the turn (I was behind one guy who went off into the dirt to avoid the clump that happened in front of him and I followed him to help the guy behind me who was getting too close), lots of spacing and staggered riding variations, you name it. I have actually declined some rides because I was in the mood for more relaxed riding. Maybe it is because there are so many different bikes and styles of riding in a rat pack, with sports, cruisers, classics all thrown together.
We should have had a video crew film us in GA to show the world how it is supposed to be done. With the best bikes for visual appeal to boot.
