By the time I got home Saturday evening whatever it was that was stuck in my air ducts was no longer moving. I believe there are three possible scenarios/resolutions:
a) That whatever it was got free and is back outside looking for some shade;
b) That whatever it was died in the heating/cooling system and soon there will be some foul air in my house;
c) That whatever it was got free but inside the house and Diego promptly ate it.
I really hope it was scenario A. REALLY hope.
