Just to be clear, definitely don't blow on the cartridge. It will only cause corrosion and can also cause mold to grow on the contacts area.... if it needs cleaning, use a dry cloth or alcohol swab.
Too many game cartridges have been ruined from years of blowing on them.
Mostly sarcastic, but there is a secret service rule that the president is not allowed to drive on public roads. The rest is all debatable because it hasn't been litigated. They answer to the president, but a president can not refuse secret service protection.
The current understanding is that they can strongly suggest things, but ultimately, they have to figure it out if the president doesn't follow.
The president can't drive by law unless on the grounds of the White House and maybe Camp David. At least while in office. They might be allowed to drive after leaving office...
It ain't years it's months ago...
