Well, I live along a branch of Lower Cook Inlet, and while we have huge tidal fluctuation it's not a tidal bore. That phenomenon happens, I believe, in Turnagain Arm, up by Anchorage. I have a vague recollection of seeing aegir/eagre/eygre once upon a time. It was probably back in 1966 when I was taking Geography 101. I've driven along Turnagain Arm dozens, if not hundreds, of times, but never at precisely the right time in daylight to be able to confirm or deny phenomenon. That's my story.
