The statewide average price of gasoline in Texas is holding steady while nationwide prices continue to fall. The current Texas statewide average price of a gallon of self-serve regular unleaded is $1.38 -- the same as last month's average. "Although the statewide average hasn't changed, some Texas cities (see attached chart) are seeing gas prices decline," says Rose Rougeau, spokesperson for AAA Texas. "This is good news for people making Memorial Day weekend travel plans."
