ForeFlight doesn't list the after hours callout #, which is in the A/FD and on airnav.com, etc. It's 580–231–0189

Came thru on a holiday weekend, service was good, fuel was cheap, facilities are wonderful.

The service here is second to none. The line is friendly and extremely helpful, the facilities are well maintained with a large community hangar for those massive thunderstorms, and Mason deserves an award for making sure folks feel like they are taken care of. The maintenance facility on the airport is run by a solid and very competent group of folks (Wrenn aviation) who have been there for many years and have a clean and well run shop that assisted me out of a tight spot (magneto replaced).
