The possum came back.
I kept checking before I put the dogs out to see if it was there ... and then about 7:30ish, Molly started going nuts again and right away I'm thinking ... it's back (said totally like the little girl from Poltergeist!)
And you know what? It was back!
And I got videos this time!
I've decided to call him Pete ... Pete the possum. Maybe Pete Q. Possum!
