Good on them i say! if they have all the money and time in the world then i commend them for trying to spend it on something that is such a posotive effort. I mean, think about it, they could just spend the rest of their lives on their cruisers and in their mansions not giving a stuff about the rest of the world, but these guys are actually trying to make a difference.
i do think though, they could choose a more realistic goal other than this beast of an effort - - like maybe saving kittens from trees or group readings at old ppl's homes
