A closer look at the number of empty stations

So thrilled and emboldened were we by the mention in NYToday that we decided to take a deeper look at empty stations since the beginning of the year.  We think the chart provides some evidence that our worst fear (of the moment) may be grounded. Yes, creeping Notspotism.

Questions we frequently ask

The fewest empty stations we've recorded? 5 on January 11
Has there ever been a moment when every station had a bike? Not this year.
The last time the empty station count was in single digits? Jan 20.
