I read about this group in my Canadian Biker magazine. Military Police Fund for Blind Children
https://sites.google.com/site/militarypolicemcrelay/homeThey do volunteer fund raising for blind children. Annually they do a MC ride from Victoria to the Atlantic Canada. Sounds like you give a $25 donation to ride with them for the day.
I'll see what more info they have in their web site, and try to keep people informed for next year Aug incase someone is interest in riding with them.
