DARIEN - The travel agency AAA is predicting a 4-percent increase in travel this Thanksgiving, with the majority of people driving instead of flying. AAA officials say more than 38 million people are expected to hit the roads over the weekend, compared to 33 million in 2010. The jump comes despite the fact that gas prices are now 46 cents higher than they were a year ago. "Easiest way to get up to Maine this time of year is to drive," one Connecticut resident says. "I figured leaving this morning, I could beat the traffic this afternoon." Metro-North officials are also predicting a spike in passenger volume today and tomorrow.
