It didn't affect me immediately, but after about 6 months my sinuses clogged and it was like torture.
It went away when I traveled away from the desert and hasn't recurred since I moved away.
I know others who have had the same problem and solution.

I never had allergy problems when I've gone to Az for a visit, but your other observations are spot on.

Phoenix has gone blue and has been there for 20+ years. It was a great place in '90. Not so in '00.
The desert flora also causes many older people great allergy problems.
The flora you grew up with, you have developed some tolerance for. Not so the desert flora.
Phoenix is full of Commifornians, Chicommies, and Michicommies.

Been to Atlanta for job contract. NFG. Atlanta NIFO.

DC NIFO. (Throw in NYC for GP)

We are a bit stuck here, but always on the lookout. Should have moved to Florida just south of Daytona years ago, but passed up the chance. Re-establishing a home base in our '70s is not an easy task. I have relatives in Phoenix, Arizona that want us to relocate there, but me and deserts only get along for a week or so. Mama still loves our house and our location, except the political climate, and we have learned to live in bad winters so here we are.

If you can't take the heat, stay out of the south. [grin]
Has air conditioning destroyed the south? It appears possible in the largest cities.

Atlanta was mostly a nice place to live 50 years ago.
Since 1974 the city government has been run by corrupt racist black looters.
The pathetic, corrupt condition of Atlanta is a result not a coincidence.

Foreign Invaders.
(Similar to D.C. in important ways.)

No chance of getting out? Alabama is nice if you can take some heat and humidity (or stay in the A/C a few days a year). And you NEVER have to shovel snow. We occasionally get snow, but rarely enough to shovel, and everything shuts down, so there's nowhere you need to go anyway!

Ohhhhhh yeahhhhhhhh..... smiling as well

The only fly in the ointment is, being residents of the Peoples Republic of NY, my wife and I have been and are being robbed to pay for their Schiff.

Agreed…..asylum from what…..exactly?
A communist totalitarian state? …….. Ummmmmm have they looked around lately?

(A contented smile slowly crept across Markus’s face. As he sipped the dark and bitter brew he thought to himself…”Mmmmm the coffee’s good.”)

Yep, stuck in their own Schiff. Should start by going back to calling them illegal immigrants, not migrants or asylum seekers. Start by being honest, commies.
