You can crease the signs into the shape of a box and glue it with a product called shoe glue. Works great. I have built remote controlled aircraft out of them. But they would make great liners for nest boxes and such.
I needed a heavy piece of wire like that to bend into a sort of Z shape to quare up my drill press table,, unfortunately I did not have a sign,,fortunately somebody along my drive home did..
that wire cut into shorter 10" lengths and bent on one end works great for holding the bottom of woven fencing tight to the ground..
collect all you can and in 4 years sell the wire to the next bunch of candidates..
I still think using them for poop boards...or rabbit cage liners is a very good use.....we all know whats being slung.....by all politicians...not that I would want that job!
I used the metal hoops to prop up my corn stalks after a damaging rain/wind storm. They are too low to be very useful for tomatoes. I have an 8' tall tomato trellis (built by my architect BF), and the tomatoes get most of the way up it! I don't see how the metal stakes would be useful for chickens. Maybe to hold down the "skirt" of a chicken tractor's metal netting?
If you can get the paper-like signs, they would be useful as dropping boards because they are coated with a waxy-type substance. I typically reuse these to make other signs, including my "Free" pile sign. (Vermont has a healthy tradition of free piles, stingy old Yankees.)
I would say that you can collect the signs to use on the floor of the coop. After all, most politicians are full of what the birds will put on them anyway. I don't know what to use the wire for, though.........
A friend of mine was just telling me that she put a sign on her lawn last night at 6:30 and when she woke up this morning it had already been stolen.
She mentioned that not only does it upset her for the obvious reasons, but she also uses the supports as garden stakes. I've also seen a lot of people cover them with poster board or cardboard and re-use them for garage sale signs.
