Not that I am aware of, although if you call they will tell you. The staff is super nice !
No. There is currently a program for first responders and linemen that allows free entry to state parks (and this is now officially a state-owned park) but there's a form you have to complete. Its good through 10/18, but I don't have a link to it handy. You could ask about it if you're a first responder.
No sure
