Arizona turned Blue because of the exodus from California.  Texas is next due to the same effect.

somewhat related tip:
latest version of macOS/iOS will automatically offer up sharing a wifi password to other users attempting to login to secure wifi if they are within bluetooth range. 

Never had any out of sync buffer delay mixing the follow:

-Direct audio attached to a Mac 
-Airplay from the Mac to 3 Apple TVs (1 forth generation over HDMI, 2 second generation over analog out) attached to stereo receivers.  
-Airplay from the Mac  to 2 iHome WS2s over wifi
-Airplay from the Mac to 4 iHome WS3 over wifi
-Airplay from the Mac to Raspberry PI attached to stereo receiver.

all the above at the same time and all are in sync via iTunes on a Mac.

If I want to my iPhone provide the audio source, I can use a combination Airfoil Satellite for Mac  (and stream to the Mac) and Airfoil for Mac  (which distributes the incoming audio to other speakers) and Airfoil remote for iOS ( to control individual volumes of those outputs).

I don't use the iPhone to drive the audio source so much as a remote for iTunes on the Mac because I don't like draining my iPhone's battery.
If I do end up buying a HomePod, I'm not sure I would utilize Airplay 2 much for that same reason.  The battery life.

Just curious. How does WiFi help with pinpointing my location through GPS better than cell tower triangulation? Not talking about ibeacons and such inside buildings.
It certainly can't help while driving as one would pass through WiFi networks too quickly to be of any use.

I think because the location of wifi hotspots is identified via crowd source data placed into online database. This is done by handsets which have GPS built in to phone home the their location when a new wifi network is seen.  I believe Android and iPhone handsets can both do this.
