was on a night flight with a student on tuesday and went into PDX, did a touch and go on 28R and on the go happened to look down and see a Horizon Air CRJ 7 or 9. Couldn't quite tell but definitely not a 200. Was parked there alongside a bunch of dash 8's on the ramp east of the terminal. has anyone seen a Horizon CRJ? i thought they got rid of them years ago and went to an all Dash fleet and haven't seen one in forever.
