You're all in my thoughts there in California...lived many years in So-Cal before I finally moved to another state. Wildfires got too close for comfort twice while I lived
there...I kept pillow cases or "snake bags" with twist wires & rubber bands (for closure) at each of my numerous snake enclosures...in a panic, you don't want to have
to look for such things. Also kept large ice chests on hand to carry bagged snakes & to help moderate temps. (either hot or cold). Very smart of you to think this way,
but I so hope you never need to do this.
