We’re talking gas prices here.

Plummeting gasoline prices over the past couple of months are expected to remain low through at least the spring, signaling generally good fortunes for the nation’s economy, said Purdue University energy economist Wally Tyner.

The national average price for regular unleaded gasoline was $2.61 per gallon as of Dec. 12. That is 59 cents lower than a year ago. Indiana prices were averaging about $2.52, and prices in the Lafayette area were even lower, averaging $2.32.
