I'll be heading to St George, Utah and Zion National Park next week and I plan on taking my P2. I'll be flying into Las Vegas and I will have the afternoon free so I plan on heading out of town for a flight or two. So I am looking for interesting locations within 60-90 minutes of Las Vegas. I was looking at maybe Hoover Dam, or Red Rock Canyon. But the problem is that these are National Parks, and as far I know the flying of UAVs is not allowed without advance permission (although I can't find documentation on the NP web site). I wonder how many of the videos of National Park flights posted to Youtube had permission and how many have just gone ahead without it? And how many are just ignorant of the law? I have sent a request for Zion, so it'll be interesting to see what they say. Any other suggestions for legal locations around Vegas?
