My current job has me working night hours in Central Park.  I’ve got into the habit of showing up for work early and sitting in the Mall to do my daily writing.  For non-New Yorkers, the mall is best explained as “the filming location for EVERY movie scene of a couple walking during the fall in NYC”.  Lots of foot traffic, but it isn’t distracting, and you can’t beat the scenery.  Being outside has also proved that not having internet access while I write is actually a good thing.
