Here's the response from KGB.
" The benefit is open to anyone. All you have to do is tell Lynn when you are registering at the park that you are there for the benefit. The park fees are the same. we will have all kinds of stuff that we will be selling raffle tickets for and some small give aways , Benefit T-shirts will be for sale and there will also be a D-J there playing all kinds of music. It would be great to she you all there, tell everyone about it. Hope to see you there. "
I replied to this email to see if there will be any food and if there's a sign up fee. Once I hear back I will let you know.
