You would have to understand my area. We are a rural area with 100% volunteer fire departments. Our fire departments are not manned 24 hours a day and most have full time jobs and family life.
I do, & I've been to Your place, & My situation is not much different than Your's.....I'm just lamenting the situation, & why it's so important to have one's own extinguisher.
I had a real aftermarket ammeter in My Killer6, one night driving in the rain one of the heavy-gauge wires popped out of the harness clasp above the column, with the wipers going fast & non-stop that linkage cut right into it quickly. Suddenly the car went dead/lights out, & the gauge started smoking, I had no wrench to unhook the battery....but did have a sharp flat-blade screwdriver. I jumped out, threw the hood up, & literally chopped the ground cable thru' w/a stabbing motion......
