Dont cross double yellow lines and speed passed any state fish and wildlife ranger either. A good number of state and federal officials are put in enforcement situations and without that authority would be severely lacking in fulfilling their jobs.
I’ve been told that in some states, wildlife and marine ranger have more authority than other law enforcement. Not sure if that’s apples & apples or apples & ooranges though
It is very common for park rangers to behave like they are the king of the park. They may have a geographically limited powers, but they consider them absolute.
