Great shot. I knew it wasn't LA proper, or the Valley, or the San Gabriel Valley ... but somewhere close (or closeish).  Just couldn't place it .... Cucamonga ... who woulda guessed.

AS .... what software are you using to do your pano stitching??  I did several panos a few years ago.  I think I used something like ipix??  Not certain I remember.

Could be worse, could be raining.
