Well, the story:
I'm north on Burrard and stopped first in line at Broadway. Both east & west bound lanes on Broadway have left turn arrows and cars start in motion. Then, from the west and turning north onto Burrard a silver Goldwing leans in to his turn and half way through he rolls on more throttle. Problem is he's running right over a man-hole cover. Now I don't notice it right away, but when the rear tire goes from paved road to the man-hole the rear tire spins and kicks out; the bike lowsides and drops the rider on his shoulder and pivoting on its crash bars the rear grabs enough to make the Goldwing do 2 or 3 doughnuts. Spinning and smoking it stalls out.
The guy is lost, almost runs back into traffic, begins asking crossing pedestrians to help heave the bike up. I was already out of my truck to help but being across the interesection and enough people on it I stopped and jumped back in. The rider and bike "finish" the corner and roll the bike into the Esso lot. I pull through on the green, into the station and park and I go over to follow up with the guy (no one else hung around). He says he has no idea what happened, so I fill him in on the man-hole cover and the lingering patch of rubber his bike left at that point to confirm it. Within 90 seconds, an ambulance comes through followed by fire rescue seconds later. Someone thought it was bad enough to call it in.
Now first, the guy was really rattled and mumbling about 30 years of riding and nothing like this happening before, but besides a complaint of a sore shoulder he was good. And the Goldwing? ..... get this: his crash bars (which really don't stand out though they are part of the design of the bike) were the only parts damaged. And unless you ran your hand under the bars, you didn't actually see it and you'd never know the bike had been down.
It was a good one to walk away from.
