I have been travelling a little more lately. The lineup at some airports have become really crazy. The part I don't understand is why is it different at every airport? At some airports you need to remove your laptop, at others you don't. Same thing with shoes. I am sure there is some silly bureaucratic reason why it changes from one airport to another.

The best part is when the TSA guard yells at you for  not taking your laptop out. Silly me! I got confused as the last TSA lineup, where they did not make me remove my laptop.  

It is for this reason that unless the distance is really long, I prefer to take the train, or drive. Trains are still the best way to travel, and much better for the environment as compared to cars.
