> The painters aim for straightness. They relish the crispness. They try to tune out impatient drivers who yell or honk or even sometimes throw things at them. But they know that unless they mess up, few will consider their work.

Ah, I know that feeling...

(And what the hell is wrong with someone that gets angry at a road crew?)

> When Garza presses a black button spraying white paint on the road, it also triggers a second gun behind the paint gun to sprinkle tiny salt-size glass beads. If the paint is too thin, beads won’t stick to it. That means the lines won’t reflect light.

I don't think they use these beads in the road paint universally. The lines here in the piedmont region of NC are virtually impossible to see at night, especially when they are wet.
