So you pull up to the border. After a quick conversation a homeland security person has a good idea, and remember they have been trained to do this, what you political leanings are - so into secondary you go. Your lap top disappears after you give them the password (or you are going back) and then they return after doing a flash download of your hard-drive and seeing what you use the computer to do. 

The agent comes back and says I see you are posting to the Globe and Mail - log on please. The agent taps the name, then taps comments and begins to read. 

You know who you people are as the conversation will go like this:

"Here is written notice that you have been denied entry into the United States, and this status will remain so for five years. You are going to get into your car and drive back to Canada. Attempt to cross back in and you will be arrested."
