I am sure there is a national Cancer charity as ive heard that at the moment representative of Cancer Research uk are in the USA to help co-ordinate fundraising ( it seems that there is an international effort in this area). I can give you an email address for Cancer Research uk in London, they may be able to give you some relevent info on where best to send donations in USA.
Could you please explain my Idea (Challenge) to them and if they are interested, my CRuk contact in the North East of england is Susan Mckenna, Newcastle office.
Please also spread the word - the more people get involved the better.
PS: to someone out there? I inadvertently deleted an email from the aikiweb. Could anyone whose sent one in the past 2 weeks please resend. thanks
