 Driving to your 4th of July holiday destination will cost you more. That's according to GasBuddy.com. The average price of gas in Baltimore rose 7 cents in the last week. A gallon of regular unleaded is at $3.56 per gallon. And while that's 3 cents lower than one month ago, it's nearly 10 cents higher than one year ago. Meanwhile, the TSA is getting ready for a busy summer. The busiest on record, Chris Mergia with the TSA here in Maryland, says that means high-tech scanners are coming to BWI.
