We got around 2" of rain yesterday, with temps in the 50's, eat your heart out 
all you desert dwellers that can't water your lawns!

Your country has scorpions too don't forget.  We offset that with copperheads 
though..

Humm, they regulate off the 5 volt line, so I'm a bit surprised a load on the 
12 volt line stabilizes it.

Boy Howdy am I ever aware of that, at 73 & counting.  I'll never get 10% of he 
stuff I want to do, done.  So each project I do get done, I have to keep from 
breaking my arm trying to pat myself on the back.  Enjoy it while we can. :-)

OTOH, I know I am not the oldest member of this group either.
