I flew out to Sullivan Indiana today and fond a nice little airport. I found a small
FBO with reasonable hours. Self-serve 100LL and Jet A at reasonable prices. I didn’t see any fuel trucks. Runways are 36 and 18 and is about 4300 ft long. Below I have included a picture of the hours of operation (sorry for the reflection) for the FBO. It is locked when not in operation, with the exception of a small set of rooms accessed on the south side of the building. this area has a Flight planning area
and bathrooms. It was clean and well maintained. I did not see a courtesy car.
I meet two people while I was there. I suspect one was the airport manager and the other just doing some aircraft cleaning. Both were very friendly. I would be more than happy to visit again when I can visit some of the local eats.
