It might sound unbelievable, after years of high gas prices, but it finally happened again: gas fell below $1 per gallon… in one part of the country, at a few stations, for one weekend.

A few Michigan gas stations had prices below a dollar over the last few days, making it the first state to welcome back those super low prices, according to GasBuddy.com and local media, including WXYZ.com.

There were signs for $0.95, $0.78, and $0.77. Then, according to NBC News, there was one station that dropped its prices to $0.47. That’s quite a discount from the current national price of $1.89 per gallon.

The super low prices appeared to be part of a local gas war in the area of Houghton Lake, notes USA Today, with police directing traffic to deal with the long lines of cars waiting to fill up.

It was fun while it lasted: by this morning, the price of regular at two stations in the area was up $1.46 and $1.47 a gallon, GasBuddy reported.

Gas prices are down across the country lately, going from $3.85 a gallon to $1.89 in the last 18 months, as the price of crude oil dropped below $30 a barrel.

Some states are left out of the discount fuel fun, however, including Hawaii at $2.63 average per gallon; Alaska with $2.34 a gallon, and California, clocking in at $2.76 per gallon.
