I love flying FPV drones for fun through obstacles and race hoops, and loved games like Ultrawing where you just fly through markers. Before Microsoft Flight Sim was out, I made this Star Wars Flight Sim in Unity where all you do is fly through race gates – https://eggman28.itch.io/star-wars-flight-sim
So when JoylessTunic738 reached out to me to suggest adding flight markers through an awesome stretch of the Grand Canyon, I thought that was a great idea.
Start point: 36.05735039634738, -112.13803483945247
Start and End Points are marked with the additional green outer ring, with about 20 markers in between with just red and yellow rings.
