It will open back up in April, I believe. It's the same schedule each year.
I think this will explain the signage you saw. At least that's the way I see it.Pretty sure I saw a sign today that said it will close on the 15th....my wife just verified that she saw it too.
I started another thread in the trip reports and have a few photos posted. Had a great day! Thanks guys!
