Temporary Features
Temporary features, e.g.:
 * one day banner, e.g. "Today is Election Day"
 * "Show Polling Place"

Today is Election Day
On US Election day 2016 (November 8th), Google Maps showed a banner just below the main top left "Search Google Maps" input box, calling out that "Today is Election Day", and prompting the user to "FIND YOUR VOTING LOCATION" (linked to same place that below "SHOW ME" button did).



Show Polling Place
Two days before the US Election day in 2016 (November 8th), Google Maps started showing a special toolbar at the top stating: With a big blue button to "SHOW ME".
 * Election Day is around the corner
 * Make sure you know your polling place



The "SHOW ME" button links to:
 * https://www.google.com/search?q=Where+do+I+vote+in+the+2016+United+States+election+%23Everyonein2016&authuser=0#eob=va/4/16/

Which is a Google Search results page with a "Where to vote" onebox form at the top (this might be more appropriate on that page)



When you enter your street address and submit the form, the onebox expands and shows you a map to your polling place along with additional information and links.

E.g. if you happened to live at 1600 Pennsylvania Ave in Washington DC:
