Nah, I wouldn't want to live in Portugal---or Montana, for that matter. For me, the joy of these places, which I dearly love, is the mental relaxation that comes with NOT working. It would be a whole different story if I was having to write for a living while staying there. The pleasure comes from switching off my brain for a week and enjoying the scenery, the beer and eating out most nights.
I'm very happy here in Scotland but I often wonder what would have happened if I'd discovered Montana earlier in my life. I feel completely at home there and love everything about it----the history, the jaw-dropping scenery and the friendliness of every single person I've met there. Next April, I'm heading out again. A couple of nights in Denver, then off to Montana and Wyoming for a week of touring. Bliss.
