I bet they went home with a story to tell! That would be awesome! I will definitely head for those places. I'd love to get lunch down in Marble Canyon.
I just don't know from the things I've read on the internet how low you are allowed to go? I've read that you can't go below the rim and some quote just the 500' rule. I think the numbers in blue on the map is just the air space that you have to monitor the frequency on while you're in there? Like a class B shelf you have the ceiling and floor of the airspace? So, from what I'm seeing is I can go anywhere, except the "no fly zones", with the usual 500' rule? To me, I'm seeing that I can go down to 500' AGL? I feel comfortable enough in doing so but I don't want to step on any bodies toes. It sounds like you grew up there and/or are local there so you would know. Better to get someone to hold your hand a little until you learn the ropes...
So, is there a pattern that people follow like stay to the right and then people going the other way will be to your left? What's the ins and outs?
