Good advice. I changed my plan. The best plan is prevention.

Be aware of your surroundings.
Make a scene. Yell "A man with a white collar is trying to kidnap me" if the guy is wearing a white collar. Hurt the perp. Decapacitate him if you can safely do so. Try calling 911 before the guy takes your phone away. If I'm not mistaken, the police will come, even if the guy hangs up too soon. Run in a zig-zag pattern to make it harder for the perp to get you.
