Love the graffiti. If I were ever to become a mayor I would work with our street artists instead of against them and try to get them some commissions with the city/town to create wonderful murals.
I also think trains in Canada could make or at least save, a pretty penny getting artists to paint their grain carriages. Work with the artists instead of against them. Mask off the numbers and let them go to town!
