Most of Mexico's provincial cities have a quaint habit of painting anything that does not move.
That includes trees, street curbs, government buildings, and probably immobile politicians. Some of the painting is politically motivated. Since each political party has its own colors, "naturally" all of the towns need to be repainted to reflect their glorious leaders political colors.
Yellow is possibly the most favored color in provincial Mexico. If there is a curb sticking above the dirt, it needs to be painted yellow. Unfortunately, the paint used is also subject to political interpretations as to quality and kickbacks and usually lasts a month or two months before the road dirt makes it appear just like it was 8 weeks ago. Usually that yellow painting effort occurs before touristic holidays or political events.
This painting nonsense came to my attention because my neighboring municipal water facility recently repainted its wall in its customary green. Today 2 workers spent a day, repainting the wall in red to reflect the colors of the current Veracruz governor.
That is just a minor item. I sincerely believe that the local municipal city hall, constructed in the mid 1950's is only being supported by the dozens of coats of different political paints applied since its construction.
I wish someone would bring one of those first world sand blasters, manned by third world personnel to Catemaco or Veracruz and reveal the exterior deterioration in the local government. (Buildings that is, ahem!)
