make a wish
 

hello,
i am planning to ride my bike from costa rica to pennsylvania (usa)....i would like to have some sort of pourpose behind my trip. my idea is to raise money for make a wish foundation.
all expenses for this trip will be paid for by me.....all money raised would go directlty to the organization.
what is the best aproach to something like this?
has anyone done something like this before and could give me some information?
why "make a wish"?.....i believe it is a good organization and its focus are kids who are sick , make a wish foundation provides children with the chance to experience things that most of us take for granite.
