Personally, I like to find new VFR routes and refine my existing ones in the western US, primarily along the west coast (I-5 corridor and cities along and around it) and some more inland routes.
This includes a lot of good photogrammetry areas directly around major cities and metro areas (the greater Los Angeles area being the biggest), and lots of autogen scenery in between. In the photogrammetry areas, I love how realistic things look – correct colors and shades, and recognizable real-life buildings everywhere!
In the autogen areas, the buildings aren’t exciting but the natural scenery and ground textures are still quite nice (though over-saturated and with a strong green tint in many areas). Mountains, rivers, farms, deserts, lakes, volcanoes; sunrises, sunsets, clouds and rain. It’s all there.
This is an enormous amount of fun for me, and I gain familiarity with areas I’ve been through before, learning to recognize where I am and where I’m going and how to recognize points of interest and places where I need to adjust my course.
And I take a lot of screenshots and share them with my friends and family, just like I do when I’m a passenger on a real plane.
I’d love more photo-based building scenery in the smaller areas I fly to to give increased realism to the buildings and cities, but I’m having a ton of fun and it doesn’t really hurt my experience.
I also recently installed the “We Love VFR” region 2 (Americas) mod, which adds more radio towers, smoke stacks, and other obstacles listed on VFR charts that aren’t always in the autogen regions. This is a nice extra touch for low-and-slow flight in these areas.
