As far as I know, no one knows where the trophy is.
Last time UW had it was 1997 over on Oahu (Honolulu). Apparently it needed cleaned or something, so one of UW's people took it to some place on the island to get it fixed or cleaned and we never got the trophy back.
That's the story I heard.
I'm on Sports Hawaii a lot and no one there has a clue where it is.
