OK, there's a scene with McGarrett talking on the radio. The camera is inside the car and the background as he's driving is the lookout/pull off on the highway overlooking the ocean. I know I've seen it prior to S02E16 - Bored, She Hung Herself (watched it on YouTube last night, the copy was awful). That aside, I know I've seen the scene before but I'm not 100% sure of the origin. But I know it's in Season 1 or Season 2.

I thought it was Cocoon but the background doesn't match. In Cocoon (where the feds are tailing McGarrett and he calls for a riot drop) the background is more industrial. He also holds the microphone slightly different than in Bored.

Any ideas? Thanks for the help!
