ATLANTA - A grassroots movement has declared today, one of the busiest travel days of the year, "National Opt-Out Day" in response to the Transportation Security Administration's (TSA) new enhanced pat-down methods.

According to AAA, nearly two million people are expected to fly between today and Sunday. Meaning many will encounter the TSA's new security measures for the first time.

The organizer of "National Opt-Out Day" says he wants the TSA to stay a step-ahead of potential terrorists.

The TSA says it has more security officers working today to handle the crowds and possible protests.
