Forrest clearing.
A designer which is located in a small clearing in a Forrest. It would be pretty good for taking screenshots of bush planes and off-road vehicles. It'd include:
-Small bush runway
-Trees
-Mud pit, as a place to take screenshots of our mud runners
-Some boulders
-Some foresty hills in the backdrop or something
-A little creek.
Picture (Imagine a creek behind the mud pit. I forgot to add it in. XD

^#Can't spell forest. XDDDDDDD

Small airport with water base for aeroplanes next to it
A similar setting to the other designer, except less trees, a paved runway, and a lake next to the runway. It would be good for taking screenshots of general aviation aircraft and float planes. It'd include:
-A paved runway, but just small rural airport-sized, may have a few small taxiways. A bit like the size of the airport on the default start location on FSX. (Friday Harbour)
-To the left of the runway, there'd be a couple of taxi ways, and then a large hill covered in trees.
-To the right of the runway, there'd be some anti-erosion boulders (or whatever they're called) on a bank going down to the lake, and then there'd be a seaplane base there.
-Oh and I forgot to mention, there'd be a little path or something that goes down to the seaplane base, and there'd be like a boat ramp thing for amphibious planes to go up and down and maybe like a parking space for some planes there also on the right side of the runway.

Note there might be a chance that this one is a little big foe the render of the designer, but oh well.
