Share The Road Costume

In the spirit of the Joe the Plumber political fad, here's my 10-minute halloween costume: a road named Share. Get it?

Step 1 Gather Your Materials and Tools

Materials are really simple:
2 cans spray paint: 1 each of black and yellow
2 ~3' x 4' pieces of plastic. rigid plastic campaign signs are appropriate and would work, but you could also probably make due with cardboard
1 worn-out bike tire
a couple feet of duct tape
a name-tag

Likewise on tools:
surface on which you don't mind getting spray paint
a pen, for writing on aforementioned name-tag
a pair of scissors
