Roving Trellises, Splashing Eggs, and Miscreants!

Today when we were leaving, I noticed that one of my trellises was missing.  Where did it go?

Oh, there it is!  On the other side of the driveway.  How did it get there?  

 And when we closed the garage door, we discovered this lovely eggy treat.    

The Neighborhood Miscreants were at it again, last night.  I'm guessing that a good citizen found the trellis in the street and rescued it.  Fortunately, I didn't find any empty beer bottles, so my Party Garden Gnomes took the night off.
