The cane reappears on the train later, and at the end Pluto's suitcase mysteriously reappears when Pete throws it at the duo in Pomona.
Continuity mistake: The car the deputy and contractor drove up in disappears. That road was one lane which would have been a hell of a back up job. Then almost instantly the 2nd car full of deputies flies up like a bat out of hell "hey what's going on" indicating they didn't speak to the contractor because they had no idea what occurred. The next sequence Casey points in direction from where the deputies just flew up. The complete opposite of where the woman was actually lying. The poor woman would have been ran over. (01:11:53)
