As travelers begin to prepare for one of the busiest travel days of the year, one thing they may not have to worry about is gas prices.

With an expected 71 million Americans planning to hit the road for Thanksgiving, Patrick DeHaan from GasBuddy predicts a drop in prices at the pump. Just how much of a drop? That's still up in the air with a looming Hurricane and trade negotiations.

After a fire at a refinery in Northwest Indiana, prices at the pump in Illinois could reach below three dollars next week.

According to DeHaan, prices typically drop in the fall as refineries switch to a winter blend of fuel for colder months.
