4: Secure a supply. Invest in & promote local 🌞🌬

@danie10 @dannyman Apparently birds have UV vision that works even at night, so why not paint (hehehe) in such a color, or a fluorescent color so people can see it also — might be useful for flying drones, kites, ultralights, etc. RAF planes had yellow propeller tips for safety of people on the tarmac... That propeller scene in (which freaked me out as a teen) was a German plane, of course, which didn't have that!
