I post this in honor of one of my local heroes: Scarlet-the Freewayblogger. He went around at night during the Bush Regime and put up huge professional looking signs on freeway overpasses that said "Impeach". One word. I'd look up and see them all over the Bay Area and decided I wanted to do it too. We had a sign making party and I made several signs-mostly "Impeach" but also "Arm the Homeless" which I put up on the offramp of the Tiburon Mill Valley Exit. It lasted a whole 24 hours at least! 

The one I liked the most is the above (we didn't put up the picture, just the words).
