IF YOU'RE FEELING fenced in some day, you may decide to take a trip to your favorite gambling mecca, where anything goes.

Before you leave, you may want to tell your friends, and while you're at it, let them know what you've been doing lately. Depending on where you are, and whether what you do sounds suspicious, the government may read that e-mail.

If you go to the town square to wave down a taxi to the airport, you may also be waving to a camera housed in what looks like a street lamp. If you look like a wanted criminal, you may draw the attention of a security guard watching a monitor, or the guard across the street.

You can bypass all that by driving to the airport, but if you keep your mobile phone on, the carrier will always know where you are by triangulation using the phone's signal.

At the airport, you may have your face scanned again. This may actually speed your rush to freedom, because if you're a frequent flyer who's volunteered to be pre-screened, you'll probably face less scrutiny before you get on the plane.
