^^ Yep, ditto. (except the bone marrow thing, wow!)
My thoughts on process, Candian or American:
1. Continue to have donation be Opt IN, spend the money on advertising etc to promote awareness, put it with the license renewal stuff, etc.
2. Also advertise that if you are not Opting In AND you could (i.e. no health issues), you do not get to receive organs either in case of emergency.
