Have you ever been in trouble in another state than your own due to a difference of state laws you didn’t know of?

Since laws vary depending on the state you’re in, I imagine confusions can happen when you’re visiting or moving to another state, so I was wondering if you have anecdotes of it happening. Maybe related to driver’s permits/traffic laws, gun laws, smoking bans, status of cannabis, age to drink alcohol…?

By “in trouble” I mean anything from a simple warning by a cop to an actual sanction.
