A Quotidian Question

.


I'm on the road again!  But while I'm making that weary 300-mile trek northward, I thought I'd posit the following question to you, in the hope that someone here can answer it:

What the heck is that plastic yellow grid on the telephone pole in the picture above?  They're common as common nowadays but darned if I can figure out their purpose.

Okay, I'm off.  Back in touch soon.
