my heart goes out to you julietbravo, having sustained a similar catastrophe 5 weeks ago (fractured distal radius requiring titanium plate). yes, it does happen soooo easily. at least we're in better nick than the poor fellow who crashed into a car door yesterday - seriously ill (made me go cold hearing about that on the radio).
on the brighter side, i've had discussions with a vollie team coordinator at BV as i was going to ride and volunteer. i'm still not sure if i can ride or not ( i've been doing daily rides on a wind-trainer/stationery bike to keep fitness up), but i've pulled out of being a riding volunteer. she said that i'd have until the end of the first day's ride to decide if i'll ride or not, and possibly become a full-time vollie, if they've got space. do give them a call, however, to verify this.
good luck, and hope you mend quick
