42 miles into a 55miler with a group I ride with perhaps 5x/yr and 4 of us 50+ got 30minutes ahead of the rest of the group trying to get back before it hit 12N. This was an area I had never ridden and we approached a moderately steep 0.5mi long down hill that curved to the right. Just before the two cyclists in front by 100yds or so disappeared around the curve, a small dog ran out and then flipped head over heels backward got up and ran off. I didn't see the cyclist dog collision but that is never a good thing for the cyclist and a deep sinking sensation occurred as I rolled around the curve and found one of the cyclists on the road, bike 15' uphill off the road. He had to doing 35-40mph when he hit the dog. Bicyclist was unconcious for about 5 min before he started thrashing around. He never came completely around but by arrival of the EMS was able to give his first name and was obviously moving everything. Later incomplete report suggests ribs and clavicle fracture. He had no idea what happened, and for that matter never ever will. Major, even minor concussions are like that. In just 2-3 seconds a major unforeseen interlude occurred in this man's life. You just don't know how good things are sometimes.
The strange thing is none of us knew each other's name beyond first names. All of us had just met that morning. He was just a John Doe til he came around further. I need to get some sort of ID that is in an obvious spot, can't think exactly where right now, wallets are too bulky, clothing sometimes is cut away, his helmet was left on the scene.
