Most of that is simply not true. Most people never even know there is a shutdown. Of those that do, most know because of the news telling them how horrible it is.It makes almost everyone angry as their lives are badly disrupted, air travel is disrupted, vacations are ruined, etc.
Air Travel is not affected. Controllers and FTA security both work during a shutdown.
Some parks get shutdown, which could affect some travelers.
Then there were the dick moves like shutting down the WWII memorial in DC.
What exactly was affected that you were badly disrupted by last time?
