We took the helicopetr trip (via ERA) and my wife thought that it was the best time that she had on the entire 14 day Alaska trip (about 1 hour ride)as she had never been in a helicopter before I have had loads of time in one with the Army so it was not as unique to me. I figured that I would probably never have an opportunity to walk around on a glacier again and the sights were spectacular (saw bear, eagles, carabu from the air

).
