Update to makeshift anti-theft ideas for yard signs

Here's an update to my post about interesting methods to discourage yard sign theft.

My neighbor went a step further with their Kerry signs. As you can see, she ran a wire to her electric fence.

Meg says:

Your "Another outdoor warning note" post reminded me of a story from a former coworker. Also a big Kerry supporter in the last election, her lawn signs were consistently stolen each night after she put them out.

Fed up, she covered the next sign she put out in Vaseline, so it
looked normal from the street, but covered your hands in slippery goop
if you touched it. The following morning she went out, and there was
the sign: slightly askew, but still intact.
