NYC, man... ;)
Humidity. There's no hiding from humidity.
When we were in NY, I was apprehending our move to Las Vegas because I thought NY was as much as I could take. I'm a northern bird - give me a Canadian spring or a Russian autumn and I'm in heaven. :) Even winter is preferable to heat, as far as I'm concerned...
Well, I'm spending most of my time outside here on the balcony w/ my laptop, and though it gets hot even in the shades, it's much, much easier to handle than NY. Even when standing directly into the sun, when you feel like you're about to melt - at least you can breathe.
I remember the last 2 summers in NY - even inside w/ the AC on all the time, it was suffocating. And we were living in a "luxury rental" (Sliver Towers on 42nd) - new buildings, great AC and insulation. But still darn hot.
We live in a small/older condo here and if/when it gets way too hot outside, I'm 100% ok w/ a bit of AC inside.
It's 72 right now. No wind. No humidity. Almost perfect. :)
