This was my second day in NYC.
The first positive thing was seeing some of my coworkers and people I've gotten to know in the Drupal community over the past few years. Not being able to see your coworkers in person can definitely be a disadvantage of working from home, so it's good to take these opportunities to meet up with them.
The second positive thing for the day was finally getting a chance to work on a bug in one of the Drupal modules I maintain. It had been sitting there for a while, so I was glad to finally get some time to dig in. It also helped that one of the people to bounce ideas off was there too, so we made some progress.
The third positive thing was explaining to a cop, for whom I'd just bought oatmeal at a small store in downtown, why I was wearing bunny ears. And a dozen other people who also asked. :)
