(As Trevor) Enter the Altruist Cult village & keep walking until you see benches with a rock towards the edge of the cliff. On that rock will be a baseball bat.
(If you enter as Michael or Franklin, they will get hostile)
Edit: In 1 of the houses, there's a ammo.(Assault Shotgun) & some other item, I couldn't tell what it was.
