Same thing kinda happend to me today. Although it wasn't a blind, just a spot that I scouted on Tuesday. I pulled up and saw the light that meant for me to move on or at least away. I said to myself, oh well, and moved on.

Still in ear shot of the spot I wanted I later saw and heard the cheers of a young one. Saw some of the ducks that I had hoped to shoot at too.

Later in the day at the dock, I saw that the ones in the spot that I had marked had a youth with them and she got her first duck. She was so proud he had to show me.

So, for me, to answer your question, I just move on, but I don't have a blind, just spots out in the everglades so it may not be the same.
