When the old Pima Savings and Loan building was renovated last year, we held our breath, hoping the sign would stay. It had been painted over years ago, but the paint was fading, and the sign was coming back just in time to be relevant again. Wisdom prevailed, and the sign was preserved. Look up high on the west wall and see: "Help End the War by Dec. 31, 1971. Join Common Cause." Oral history has it that the east side of the building had a sign back in the day as well, and we're waiting for it to reappear too. What did it say? "Impeach the President."
