The roads are going to be crowded this Thanksgiving, with 42 million drivers expected to travel the highways and byways of the U.S. According to AAA, they’ll be enjoying the lowest prices at the gas pump for the holiday since 2008.

Retail averages have fallen for 17 straight days for a total drop of $0.15 per gallon, the travel and leisure group said this week.

The current national average gas price is $2.07, but more than half the gas stations in the country are now selling gas for under $2 a gallon. The rest of the U.S. is slated to hit that mark by Christmas.

Drivers may be even more grateful when reflecting on gas prices past: last year on Thanksgiving the national average price for a gallon of gas was about $0.75 more.

The most fortunate drivers are those buying gas in Indiana ($1.82 a gallon), Ohio ($1.83), and Oklahoma ($1.85), while the most include Hawaii ($2.83), California ($2.73) and Nevada ($2.59).
