Wow, I just read your first post on this and it's so matter-of-fact, and starting with the happy part (how well your bike climbs), I almost couldn't believe what came next!!

It's really maddening that this irresponsible person has totally ruined your ride. I hope you heal well (I also encourage you to get the rabies vaccine, sadly...) and that your next million rides on the mountain goat are great!
