My friend has some $$$ burnin a hole in his pocket and wants to know what the best, least-overhead, bang for the buck organization he can donate to to help veterans in need. By least overhead I mean where your $$ goes to actually helping the vets, and not feed the machine such as what I'm sure happens with all that pink ribbon stuff for breast cancer.

I did a weak search and didn't see a similar thread, and because it's an important topic please go easy on me, repost/search police.
