Today is the day to send in your tea bag. In short, the purpose is to let it be known that you are against a lot of government intervention.
Although the tea bag was supposed to be sent today, the goal was to get the bag to the government office by April 15. Chances are it will arrive on time if you send it on the 2nd. So go ahead. Send your tea bag in. Don’t say “I’ll do it later.” Go do it now.
