The visitor that came the longest distance for Heli Fest is probably the MH-60S that the US Navy sent from North Island NAS down on Coronado Island near San Diego. They had needed one fuel stop to get there with a transit of about four hours each way. As with all of the military assets on show, they got a lot of attention from the visitors. The aircraft was open for anyone to check out and the kids certainly seemed interested. Since they had come so far, they were not just having a day visit. They had arrived the day before and were not heading back until the following day. Consequently, while everyone else was departing, they were locking up the helicopter for an overnight stop.
A few years ago I was on a visit to NAS Fallon. As part of the visit we headed to the hangar used by the local search and rescue unit. They were just in the process of transitioning from the Huey to the Seahawk airframe. The Huey had been painted in a bright white and orange scheme and there was some discussion as to whether the Seahawk would get the same treatment. Would it get to look like Nemo. The thought was that low viz would end up being the rule.
At the time, their new Seahawk was in a hybrid scheme. We were pleased to see it since it was thought it might not last. As it has turned out, they have adopted some far more vibrant colors on the airframes since according to the images I have seen online. Hopefully I will get up there again some time to see what they look like now.
