"RETIRE UPTON." That outdoor board on Cleveland Avenue (now gone) showed the courage of a rabbit. A political ad requires a sponsor signature. At first I thought this ad was in trouble. Then I saw letters about 2 inches high tucked in the right-hand corner. It looked like an underline. It was hard to read even if anyone cared enough to stop, park and walk to the billboard base. I didn’t want to. I suppose few others did.
