Adjoining apartments display No and Yes signs in their windows in in Edinburgh, Scotland, Tuesday, Sept. 16, 2014. The two sides in Scotland's independence debate are scrambling to convert undecided voters, with just two days to go until a referendum on separation. Anti-independence campaigners are pushing home their message that a No vote doesn't mean the status quo. The three main British political parties are promising Scotland greater powers, including tax-raising authority, if it remains part of the United Kingdom. The Yes campaign says the promises are vague and reveal the No side's desperation, with polls suggesting the outcome will be close. Scottish Deputy First Minister Nicola Sturgeon said the only way to guarantee the real powers we need in Scotland is to vote Yes. (AP Photo/Scott Heppell)
