In California, it's not illegal to discuss your wages with your co-workers, despite what your boss might say.
Edit: I'm a lawyer in California. I assume it's the same in the other 49 states, but don't want to speculate.
As a former lawyer (UK), I lost count of the amount of people that thought jaywalking was a crime.
Unless it's a road that specifically states 'no pedestrians' or a motorway, no such offence exists here.
