My girlfriend and I were hanging out at a lake east of Issaquah near seattle and suddenly two Growlers came down low over the lake and we were subject to two sonic booms which was amazing. They sounded sort of like a resonant crack of thunder but much louder. They flew over a boat in the middle of the lake and I shit you not someone on it screamed "AMERICA F YEAH." It turned out this lake was one of the ones they filmed for the new Top Gun film, but it was common for Whidbey pilots to buzz it on their way back to the NAS.
