Question for you Ohio and West Virginia natives

[schnowz]

  Just got back from a loop down to Deals gap, Georgia and back thru KY and 
OH\WV  - so many roads so little time...
I found myself on a Ohio road we were on last year quite by accident I came 
in from a different direction and had a Deja vu feeling before realizing it 
was a spot i had taken a pic of last year. Got to check out some nice new 
roads with the help of GPS this time..

 Question for you Ohio and West Virginia natives-  what the hell are these 
things hanging in the trees?
