The President's Glasses in Bloomington, MN

The Irish President has some Very Important Documents to sign at Dublin Castle, but without his glasses, how will he do it?
Luckily, the Presidential Pigeon knows exactly what’s happened, and follows the Presidential car to Dublin Castle, taking a bird’s eye view of the city on his way.
But the pigeon gets stuck in traffic on O’Connell Streetbumps into some tourists taking selfies at Trinity College and even beats a Viking ship in a boat race!
Will he ever catch up with the President to deliver his glasses in time?
