Ah.. the joys of "weather"

Have I explained yet that I hate weather.  Really.
.
People who come to LA complain that there is "no weather".  It is always sunny (with low clouds at the beach that will burn off after noon) and reasonably warm.
.
Damn straight!  It's ALWAYS not a factor (except Santa Ana Fire Weather or Earthquake Weather - but both make for crazy good times out - so that's okay).

Today Eddie learned yet another joy of "weather".  In his brand new BMW all 4 of his tire monitors went off.  Low pressure warning - and the book said "Don't Drive It!".
.
He took it to the shop this morning and it turns out ... weather.  You see, since we have owned a car, the new tire monitor systems have gone into production.  AND (I found out this morning) tires lose 1 psi per 10 degrees (they weren't clear if it was 10 degrees C or F, but it hardly matters - it's ten units of weather).
