I stopped by in a C150 this past summer. Self-serve fuel is easy to use. I needed air in the tires, and the employees inside the FBO building were very helpful. Their facilities are essentially brand new featuring a kitchenette, flight planning area, and lounge. It was very nice, especially considering the size of the MCX Airport.
I take all of my private pilot students here to satisfy their 100nm night cross country requirement. The students are always amazed at the elegance of the FBO, from the design of the building to its amenities inside. The staff here has always been helpful each time we've come in, usually around 9-10PM. This is one of my favorite destinations because of the FBO.
