Thanks, Rob, for your carefully carved topic delineation, and for Lorrie's fine response. To answer most succinctly: *Why? Myriad reasons, as we know. The old herding cats, etc. *Problem? Depends upon conditions, distance, visibility, radios, paddling abilities, interpersonal knowledge, etc. *Fix? Just a couple of 6AM thoughts: Never let the slowest, or weakest, or least experienced paddler lag; aside from inherent risks a laggard's mounting fears of increasing distance can easily overtake any inherent paddling pleasure (lest one think a subsequent adrenaline push stimulates a newbie, please remember that CAM-paddling isn't an S&M activity) AMEN, brother! As somebody who spent her first two seasons consistently being in the back of the pack I couldn't agree more. And, I must acknowledge, that I have improved my abilities I sometimes am at the front & like it so much I stay there without dropping back to check on others. I do frequently turn around however,,,
