 AAA is forecasting a record July 4th travel period. Although with nearly 90 million people under heat alerts, it might be a good idea to watch the fireworks from a boat or on TV with a bowl of ice cream in hand. The Motor Club projects 70.9 million U.S. travelers are heading 50 miles or more to enjoy Independence Day festivities this week. That's a 5% increase over last year and over 5.5 million more than before the pandemic. About 60.6 million are going by car with the worst traffic on Sunday.
