Have an "Open Day" with pony rides, face painting, BBQ (ask a local butcher and bakery to donate sausages and bread, then borrow someone's BBQ so it doesn't really cost you), and ask places to lend things like cotton candy machines and slushy machines. They're usually happy to do it in return for a bit of publicity, like a sign for their business saying they helped out or whatever. See if you can convince a local band to play live music. Do a big speech talking about the work you guys do and how you really need donations; not just cash, but gear, feed, etc.
