It’s been years since I’ve been there, but KRS has always been awesome to me. If they’re being run just as well now as they were then, I can’t recommend them enough:
My first time there was in a piston twin - a last minute divert to GGG for weather. It was late Sunday and they were getting ready to leave for the night, but stuck around for me to arrive, put the plane in a hangar to protect it from potential hail, and then gave me a ride to the hotel. Probably bought 50 or so gallons of 100LL from them the next morning, and wasn’t charged for anything else. They treated me like a king even though I wasn’t burning kerosene.
I never forgot that experience, so later on in my career I fuel stopped maybe a half dozen times at KRS in various jets over the years. Still got the same great service. This would all be in the 2004-2011 time frame so it’s old data, but if they’re still half as good as they were then - they’d be my pick.
