Here in Washington, construction workers wear these t-shirts with 3 large NEON green horizontal stripes across the back, presumably for enhanced visibility. Coming from California, I'd never seen these before and didn't realize it was it was a type of safety uniform. But, they look just like the Gay Rights tees which have 2 large bright green horizontal stripes, so for a while I thought it was just a variation of the theme and that all these guys and gals in hard hats were on the job advocating equal rights. I was like, Oh Washington is so progressive! :le derp:
