Water TruckSpotted near Vicksburg by Mark from Pismo.
"This gentleman just bought this 2000 gallon water tank truck in AZ and is headed back to CA (unfortunately empty - though he says water is cheaper in Ca). He gets water from the city hydrants and delivers it to big fires. He can refill 4 fire trucks or provide 8 showers for a day to hundreds of firefighters. He also has a 3500 gallon truck that fills up in 15 minutes!"
