When you go on a business trip or vacation it might be a good idea to inform your bank of your travel plans, so they won't block your debit or credit card suspecting fraud. They had to put a lot of travel flags on our account as we had to drive from California to Massachusetts for our road trip.
One of our sightseeing spots was Mount Rushmore in Keystone, South Dakota. The Avenue of Flags leads you to closer to the carved mountain. The avenue shows the flags of the 56 US states and territories.
