non profit organization

[calib]

i am a disabled vet looking for a non profit group that does work with disabled vets in the feilds of hunting and outdoors. i daho has recently started a program where nonresident disabled vets can hunt idaho for very cheap, but you have to be associated with/ member of a non profit veterans organization that deals with disabled vets. the internal revenue code needs to be a 501(c)(3)

any help would be greatly appreciated
