The national average for regular, unleaded gasoline has fallen for 35 out of 36 days to $2.21 per gallon and sits at the lowest mark for this time of year since 2004. Gas prices continue to drop in most parts of the country due to abundant fuel supplies and declining crude oil costs. Average prices are about 55 cents less than a year ago, which is motivating millions of Americans to take advantage of cheap gas by taking long road trips this summer.

The best news for consumers is that gas prices have once again dropped below $2 per gallon in many parts of the country, which is something that drivers have not seen during the summer in more than a decade. About 1 in 4 U.S. stations are selling gas for less than $2 per gallon today, and consumers can find at least one station selling gas for less than $2 per gallon in 36 states.
