If you are in Manhattan during the attack, how would you escape?

Say if you were one of Rob's friends attending his going away party or a tourist taking in the sights of Midtown, what would your escape options be if Clover comes ashore and begins it's rampage? How would you and your company be able to avoid the chaos to leave the city in example: crossing the bridges and tunnels? Would you rely on the Military and their transportation or provide your own escape? Please let me know what are your thoughts!
