So we meet at Tim Hortons for the weekly butter chicken ride / eat. There's around 8 bikes, a few regulars, plus a couple of newer riders who haven't ridden with us before. I lead us off towards river road, with one of our regular group sweeping as they didn't feel like ripping it up that night. So we take off down river road, i'm looking behind me every so often, including full looks over the shoulder to make sure i can see everyone. No-one is signalling anything is wrong so we keep going. This happens down bridgeport as well, almost as far as the airport. We get stuck at a light, and someone mentions that someone is missing - i look round and sure enough there is a member of our group missing. Thinking everyone was with us not so long ago, and we're almost at the airport, i decide to carry on round the loop and wait at the start, while the others head back down the way we came to look for the missing rider. Turns out the person who'd left us "on bridgeport", actually didn't make it away from Tims - for reasons unknown to me at this point they'd binned the bike. We'd basically ridden for around 30-40 minutes without someone and we didn't know they weren't with us ..... The others made it back there and found the ambulance etc on the scene. The person involved is ok, which is the main thing of course. As for the bike i'm not so sure.
So basically lesson learned:
1) I didn't consider 8 to be a large group, but now i'll be splitting it into 4's unless the group is 100% people i know and trust.
2) No-one pointed out that the rider was missing as we're going along - most experienced riders already know this, but if you're a new rider or new to group rides - WATCH OUT FOR YOUR WINGMAN. Keep looking in the mirrors, if someone slows down or stops, stay with them. No-one rides alone. Leading the group all i could see was a group of lights behind me (some with full beam on which didn't help). Help the leader of the ride by making it obvious someone isn't there - use the horn, flash your lights, or just slow down and stick with the slower rider if they're alone. The person in front of you should notice that you're gone from the group as well and can alert everyone else.
3) I should have checked with the newer riders that they know group etiquette, and that they're aware they should be checking for problems with the people in front, and making sure they can see and check the people behind them. If everyone had checked for the people immediatly next to them and notified the other members of the group, this wouldn't have happened and we would have been at the scene of the accident almost as soon as we'd left it .......
For the person we left behind, we've already spoken but i want to say again that i know we all need to hang our heads for leaving you there. Pleased you're ok - get well and riding again soon
