Well, it looks like we now have all the answers. I was wrong about the leak being outside zone one. I had forgotten this particular nozzle (So far from the zone valve) was part of the pack.
The stump you see next to the break was some kind of attractive weed I guess, as I never planted it. It was over 8' tall, and looked like some kind of palm tree, so I mistakenly let it grow, as it clearly caused the break.
I've attached 3 pictures as requested. You can see how close it was to the PVB and the air conditioner
When everything is back together and checked out I'll submit a final report to this thread. With Christmas so close it may be a week or two. Thank goodness things are cool here in Florida and the lawn needs far less water than normal. Thanks again for all the help.
