HORSEHEADS, NY. -- It very well may be more expensive for you to return from a weekend out of state getaway than it was to get there.

While prices for a gallon of 87-octane gas in the greater Pittsburgh area hovered between $3.99 to $4.09 on Saturday, just across the line in Southern New York State, the same fuel cost as much as $4.31 a gallon.

So if you had an empty 18-gallon tank it would cost you roughly $5.76 more to drive home to the Commonwealth.
