The backs of political campaign signs make for great freewayblogging material. The day after the election, feel free to collect as many as you can – you’ll be doing the campaign staff a favor. Campaign signs are lightweight and sturdy and usually the backs are solid white: perfectly suited to the task.
Campaign signs also make for a good barometer of where signposting is officially sanctioned in your area. Wherever people have posted signs for local candidates and initiatives on public property, that’s where you can put your own signs.
