 Record travel predicted this weekend as tens of millions return from July 4th trips. More than 60 million people expected to hit the roads, says ABC's Morgan Norwood. Morning is going to be the best time to get going before 10 is ideal. 7 p.m. or later is also a safe bet. Just know this, whenever you hit the road, it's not going to cost you any more to fill up. The national average for a gallon of gas right now, 351, just about what it was this time last year. And the TSA expects to screen more than 3 million air travelers tomorrow.
