I think I may have saw my first Growlers. I was driving past the airport (SDF) and saw four F/A-18s parked with wings folded. The first thing that struck me as odd was the huge wingtip pylons. I know realize that those probably weren't pylons but rather built-in ECM. They were all two-seaters also. The tail code was AC. That is Carrier Air Group 3. I noticed none of the tails were painted like some of the transient naval aircraft that come through.
