The only problem with leaving 'space' is what JC said. Some yahoo will cut into the pack with disasterous results.

It happened on the San Juan Bautista GTG. Some SUV decides there's just enough room for him to squeeze in. He makes the move all of a sudden then immediatly hits his brakes to keep from running over the bikes immediatly in front of him, causing all the bikes behind him to immediatly jump on the binders.....with bikes going in the other lane and onto the shoulder to keep from hitting him. This happened in a pack that was riding staggered (so called safe zone)......but it's not safe when a cage decides it's your problem if you hit him.

This is exactly why I say you should never allow enough space for a four wheeled vehicle to enter the pack. I know, I know......HOG teaches differently. And that's exactly why pack riders and HOG riders have a difficult time riding together on these GTGs.

Just like some of us think 10 mph over is a good safe speed while HOG teaches to never go over the speed limit. What are ya gonna do?

Back to the topic......what's really incredable is that 26 bikes went down on the freeway and only two went to the hospital in critical condition. Sounds to me like God was ridin with them.
Terry, keep us posted. Let us know if it's your friends.
