Enter the park at your own risk

Breathtaking and real:
By entering ... you are agreeing that we owe you no duty of care or any other duty. We promise you nothing. We do not and will not even try to keep the premises safe for any purpose. The premises are not safe for any purpose. This is no joke. We won't even try to warn you about any dangerous or hazardous condition, whether we know about it or not. If we do decide to warn you about something, that doesn't mean we will try to warn you about anything else. If we do make an effort to fix an unsafe condition, we may not try to correct any others, and we may make matters worse! We and our employees or agents may do things that are unwise and dangerous. Sorry, we're not responsible. We may give you bad advice. Don't listen to us.
Read the whole thing.
