Glad I live in Az. We don't change. Only problem I run into is keeping track of what time everyone ele is on. One daughter lives in Washington state so in the summer we are same time, in the winter she's an hour early. Mom lives in Tx, opposite problem-summer 2 hrs ahead, winter only 1. And Las Vegas Nv is our closest airport, so you gotta know what time it is in Nv if you're catching plane! Oh, and I have to take my cell phone off auto update, because the phone doesn't know Az doesn't change! So, I'm not sure that not changing is any better than changing, after all! :-)
