Any ideas floating around out there on what to do with extra fence pieces?
Brian, I would suggest keeping in case you need for repair. Since it's vinyl I'm not sure all can be painted but there are cute DIY projects especially for fall/Christmas by putting together, paint then stencil Happy Fall, Merry Christmas, etc. on each side or stencil face of scarecrow . Google and take a look at some....lots are wood though!
We build a little firewood shed from fence posts when we took out a dog run! https://www.charlestoncrafted.com/building-a-wood-shed-from-old-fence/
I used (cedar) fence pickets to build planter boxes... I'm sure vinyl would work equally as well! I hope this helps!
You could use them to surround your ac system
