Check out Ryan Whitford's latest creation, Northwest Arkansas Regional Airport (KXNA). This is Ryan's second scenery and from what I can see, he has pulled out all the stops. The ground textures are high definition and include realistic taxiway markings as well as parking at the gates. There is a large hanger complex across from the main terminal area, complete with a FBO and Avionics facility. Ryan has also realistically modeled the taxiway signs and 3d runway & taxiway lights.
The night textures are very well done as well, this includes 3d taxi and approach lights.
I would highly recommend downloading this scenery as it is free you have nothing to loose. The scenery can be found on avsim by searching Northwest Arkansas Regional name.
