Anyone make their own windshield washer fluid?

What part of AZ are you in? I'm guessing it must be up north. It never gets cold down here in Yuma. Maybe a couple nights that it drops to 30's or 40's.

I was wondering where you are, and why it say's Mexifornia on your info. (I think I can guess why that is now)
Prescott Valley here, just about 8 miles outside of Prescott.
It doesn't usually get down as low as 6 but has and probably will at some point (global warming an all):D

Yuma?, ugh.
I was over by the river near Laughlin Nevada a few weeks ago and thought "Why the hell would anyone want to live here?" and the obvious answer seemed to be the river.
Rivers are nice, but not that nice.:D
