I am a 100% disabled Vietnam Combat Veteran. I have a card that let's me in state and federal attractions. Am I covered or still pay a fee.

You will need to contact them directly. This is a private attraction.

I would also recommend contacting them directly. The owner is very involved and interested in guest satisfaction, and depending on your disability, I would imagine he is interested in making accommodations to help you. That also said, depending on your disability, it might be difficult to experience everything here. Also, there is a zoo across the street that seems similar (I missed out on it due to rain).
