If your blind was near Snohomish on the Ebey Slough.
I may have found it. The floods have sent it down stream

Unfortunately I don't think it's salvageable as WSDOT and/,or Snohomish County crews will most likely crush it with the excavator claws to remove it before it goes under the Hwy 2 trestle bridge.

A good note is your floatation is working
