bicycle accident in a group

I was in a nearly an identical situation one time, we called the ambulance.  A couple stayed with the bike and the others rode back to the a (only 20-25 minutes away) and brought a car back to get the bike.  Those situations do make you step back and think.  I've seen a few too many such accidents on group rides, but I feel more comfortable w.r.t. cars and visibility when I ride with groups.  Sometimes you wonder if the helmet needs something that goes along the chin.  Always good to have a few dollars, a cell phone, and identification with you. 

I did not really know what to do either, but the group did as a whole.  I wouldn't feel bad, now you know and next time hopefully you (I) can pass along what I have learned helping someone else out.

1.5 hours to wait for a ride is way to long.

I agree with others call 911.

When I was in a bad bike crash..head first into caution metal street sign going 24mph. I was awake and talking and sitting up. I knew who was the president and where I was but not that I had 5 kids or my parents were visiting. 

They put me in a neck brace and put me on a stretcher strapped down after having CAT scan and other tests they allowed me to move.

I have no memory of about 2 hours. My husband took pictures of me and the adventure on my request otherwise I won't have a picture or really know anything. Kevin says I sounded like I was drunk the way I was talking.

I share this because I was talking and uprigth but clearly not okay. They did debate sending me to the hospital as I could answer simple questions.

Doctors said I had a quite severe concussion maybe 85 out of 100. 

I would still call 9-1-1.  If you choose to refuse treatment, it falls to you.  But I have no way of knowing if you have a bleed starting in your skull as a result of the trauma of the fall, which will gradually increase pressure in your skull, and ultimately force your brainstem down the spinal cord, where the pressure causes you to stop breathing.  But you will have been unconscious for several hours, having grown increasingly confused, incoherent, and likely combative.

And if you tell me at the outset of a ride (or any other potentially hazardous activity) not to call 9-1-1, I will still ignore this.  Or we won't ride together.  But I do not want to be sharing the responsibility for a friend's death.

Exactly correct!

As a former combat medic with the US Army, I can say for sure that Moanbruner knows what he is talking about.
