Help with Airmap

[Mikep47]

OK guys, in my younger days I could probably figure this out easily. In the Airmap app, I understand that the red circles mean restricted-NO flying. But am I to understand that with each yellow or orange circle, I must get approval to fly? Or is this a case for being cautious? Some of these circles represent crop dusting services with dirt runways. I would be hard pressed to even find a phone number. I live in a fairly rural area, with the closest "controlled" airport about 60 miles away. It would have been nice had there been a legend on the page to describe what I'm seeing. Hope someone can clear this up for me. Thanks.

Have you hit that red arrow? It will tell the type of airspace and the ph.# to call. At least call them and see their response to your call. I know some are really hard to coordinate with. Work out something, it's that important. I text my buddy who has an airfield near me. He doesn't need to text me back, but he got the information.
Take the time to go through Airmap. They have all the rules listed.
