I agree on formal introductions (prolly twice like Mark says). This cruise was a cruise/rolling shots event so that likely added some complexity. I think we should have a set of ideas for either or cruise or a rolling shot/cruise, as one would be easier/different than the other as far as manageability. Certainly smaller groups, right turns only would help people keep up in general.
Someone smarter than me can help with that when the time comes. For instance, for a rolling shot event we might want to circle back and redo the same part of the road several times to get all the cars in. You wouldn't have to do that with just a cruise. You might even want those as separate events. Just thinking out loud on the keyboard.
