I've been gone for about a week and a half....
and it is actually quite notable how glad I am that I'm not going back any time soon.
I will really miss family and friends, and I will also miss the fascinating ecology/climate/natural history of California... but nevertheless, I am really glad to be gone.
It's funny how I didn't even really understand how badly I needed this change until it happened. There's no going back now, and I find that I am looking backwards a lot less than I was previously. This should be a good two years.
