It's been a few years since I last worked in the city of San Francisco and even longer since I lived there. I still get the emails and text messages from the city government's safety alert system.
Some of the alerts are still interesting, such as the tsunami warnings. Others are more mundane, such as street closures and other traffic related ones.
When I was both living and working in the city, I tried to be prepared for emergencies, so the city alert system subscription made a lot of sense. Post 9/11 and around Katrina we all were subjected to disaster awareness. And 2010 has shaped up to be a year full of global disasters.
Now, I am thinking about unsubscribing, at least from the text alerts that go to my cell phone. I think I can still handle the email alerts.
I should look into whether there are similar alert systems for my current cities of residence and workplace.
