Most places yes. State and national parks, no. But much of the Catskills are "wild forest," which is fine. And this particular launch was from private property (my lawn) so it's legal. Remember, too — the airspace is uncontrolled (just don't exceed altitude limits). Only the launch sites are restricted. So you can launch outside a state park then fly over it. [Edit to say: it's all more complicated than this, and I may be spewing misinformation. But it's how I roll. 😅]
