If you're heading out for the holiday weekend, you've got lots of company. Triple-A says 40 million people will be traveling this weekend -- with about 87 percent of them -- or 34 million -- on the highways. Spokesman Justin McNaull says even though the price of gasoline is averaging around a dollar, 90 cents a gallon -- the highest ever for a July Fourth weekend -- it doesn't seem to be keeping people out of their cars. And he notes that when you consider gas was over two dollars Memorial Day, driving is almost a bargain. McNaull advises people who are flying to allow plenty of time. He says delays were running up to four hours at Atlanta's Hartsfield International Airport yesterday.
