Looking for a non-profit.

Not sure where to post this, so if it is in the wrong spot I apologize. I am looking to write a grant for a non-profit group. It is for a class I am taking and I have pretty much free range on what group I choose(as long as they have 501c3 status). I would love to write one for an outdoor group. If you know of one, or know someone to contact, I would appreciate it if you shoot me a pm.
