Are you enjoying the falling prices of gasoline in the Rio Grande Valley?

According to gasbuddy.com, in Harlingen the prices vary from $1.86 to $1.93 a gallon and in San Benito fuel is selling at about $1.93. In Brownsville, the prices range from $1.89 to $1.99 per gallon. In McAllen, you can find gas for as low as $1.95.

Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday that falling crude oil costs are the main reason for the decrease at the pump.
