Hello, my name is Ralph, manager at Muhlenberg county airport, identifier M21. The fuel is self serve through two new 12,000 gallon fuel systems. 100 low lead gasoline and Jet-A with additive are both available. If between normal business hours and I am in close proximity to the airport terminal I will be more than happy to fuel your aircraft. We have a nice crew car, and there are numerous restaurants near by. Problems after hours call me on my mobile, 270-871-8996. Have a great day!
