 The extended Fourth of July period is expected to see record numbers of travelers. More than 60 million people expected to drive by the time it's all said and done. And ABC's Morgan Norwood says tomorrow could be a historically busy day at airports. TSA expects to screen more than 3 million passengers tomorrow. That's going to be the peak travel day. And look, we are already keeping an eye on cancellations and delays. So far, it's looking pretty good. But with storms looming in the forecast in parts of the Northeast, that number, of course, could change.
