Triple-A is expecting a record number of travelers on the road and in the air over Pennsylvania this Thanksgiving. The agency predicts nearly 80 million travelers will travel to their destinations next week — an increase of more than a million travelers over last year. A bulk of those travelers-an expected 71.7 million, will travel by car. On that note, gas prices are lower this year, which helps boost the number of travelers. Next week, falling oil prices may push the national price for a gallon of gas below three dollars for the first time in three years.
