For this weeks tip, I’m going simple.
Being from the New York City area I subscribe to Notify NYC, a public messaging program offered by the City of New York. It offers information on everything from fireworks warnings to emergency incidents with areas to avoid. While it might be a bit much to subscribe to such a service if you’re just visiting for a few days you can always follow their Twitter feed. Typically the same information is provided and it might be enough to keep you out of trouble.
Of course many other cities have such services outside of New York City. If you’re going to be in a location for a few days or more, it’s worth looking into the services of that city.
