Where I am in the Pacific NW (near Seattle) snow is a rarity. It's that rain that will kill you! LOL. Although seriously, our weather patterns have been changing drastically the last two years and our winters have been really dry. We're a bit worried about keeping that "evergreen state" designation at this rate!
If you have an indoor ring with lights training in the winter is no problem. It never gets that cold (we think it's an ice age if the temperature drops to 30) and it doesn't get that hot in the summer either. Like, people are sweating hard at 80 and if it hits 90 they claim it's too hot to move.
Then again, that's because most of us don't have A/C to deal with that weather like areas that get it frequently.
There are mosquitos but no biting horse flies, poisonous snakes, or other nasties. The worst we have is two kinds of poisonous spiders. Oh, scary. I've been here 23 years and never seen one.
No tornados, tropical storms, or other devastating seasonal weather. We have several volcanos that periodically think about going off, but unless you live on the slope of one the worst you're going to get is ash even if they do ever blow. We get earthquakes, but only rarely and usually minor. Again, the occasional devastating one in any given historical period.
Housing really varies all over the state, but no matter where you live the developers are moving in and trying to take over.
There's still some great horse property though. East and West of the mountains are REALLY different, you can get a whole different climate in one hours drive. It's a nice place to live though!
