Went for a ride out Soledad Cyn, and headed back south on Angeles Forest Hwy. Decided to go Upper Big Tujunga to Angeles Crest, and ride up a ways, no set destination. Pulled off a few short miles up at Charlton Flats to take 5. Quite a few gawkers sightseeing, or turning down the side road to go hiking. Plenty of bikes, slow and fast types, and the car squids. Too much for my liking so I headed back down. Did not get too far and all of a sudden another bike was on my tail. A dual sport, wtf? I moved right and he went by and it was a Sheriff with flashing red and blue tail light. I decided to not keep up with him, he was moving, and this can't be good. Couple more miles on a whole bunch of bikes and cars are stopped on both sides of the road. The other side / uphill lane is blocked completely, and it looked like someone was giving someone chest compressions in the middle of the lane. I assume the MC sheriff was there, but did not see any cops, fire, ambulance at the scene. Must have just happened. Glad I missed it. Hope the rider(S) are OK, but that did not look good. Hope it was nobody I know, or you know. Think I'm staying off that road for a while. RIDE SAFE OUT THERE.
