INDIO, Calif. -  Grandma Tina, as the students call her, not
only works at James Madison Elementary School in Indio, she has
two grandchildren going to school there as well.  "I'm very
upset that people nowadays just come in and vandalize our
properties,” she said.   "We had some people who needed some
money and they cut off the main water pipes leading from the
streets to the school,” James Madison Principal David Karlquist
said.   The new valves, like the stolen ones, are made of brass.
Principal Karlquist said the thieves probably thought they were
made of copper, which is worth more.  "One of the things we're
looking at is possibly caging them in so they're a little more
difficult to vandalize,” Karlquist said.   Something that's
priceless - water.  "We've had busses shuttling students to and
from Johnson Elementary School to use the facilities. We have
porta potties now. The busses were in place until the porta
potties could be delivered,” Karlquist said.   Grandma Tina
drove that bus all morning. Someti
