Guerilla Public Service. If you've not heard of Richard Ankrom who fixed an exit sign on the 110 freeway, check it out. He made a documentary about it (and there are countless other videos on YouTube covering the story). [VIDEO] He did it so well, the modification stayed in place for years. If you can do it right, I say go for it.

Reminds me of the "Guerrilla Public Service" vigilante[1][2] from 2001, he added an I-5 sign notification where people commonly missed the exit. [1] [LINK] [2] [VIDEO]

Reminds me of the story of Richard Ankroms, who installed his own Interstate 5 exit sign. It hung for 8 years. Video of the process: [VIDEO] [LINK]
