The economy is expected to affect holiday travel this weekend.

Thanksgiving travel dropped by 25 percent between 2007 and 2008 and the American Automobile Association says those habits will probably stick around this year.

About 38 million people are expected to go somewhere over the holiday weekend. That compares to 58 million in 2005 when the economy was better.

The travel trend may also be good for our health. The Centers for Disease Control is urging people to travel only if they are well. The agency is concerned that holiday parties will wind up spreading the swine flu.
