make-a-wish is great dude, maybe donate to them every so often and sometimes do something more local? like the food shelf idea. 500 dollars could go such a long way for a place like that, and that way you know for sure that you are helping local people who are unable to feed themselves.
not to say make a wish is a bad place to donate at all, but i just feel like 500 dollars would be best served in a smaller charity.
youre doing a really good thing though, thats awesome.
