¿Is there a bright side?
Sorry to hear that. It was your bike, with all the ducttape. I hope you maybe get it back, but then again, a part of me says you weren't really wedded to that bike, maybe instead of that Antarctica Cruise (Alistair still gets to go!), you get to try out that "smaller bike is better" thought and maybe this is your silver purse, or whatever it is you get when shit happens for a reason. And the adventure goes on.
Good luck on the recovery of the bike. Having something to trade in is a much better route to a new bike.
Can't wait to see what you´re riding in Viedma.
