Well, I don't actually dream of getting away and being able to focus on writing. Getting away, yes, but I have no yen for focus. The one I dream about is the six week long writer's workshops, because of the chance to interact with other writers, and get intesive critiques and so forth. As for perfect location... a log cabin in the rockies (or even more special would maybe be the alps?) sounds ideal to me, as long as it has internet access. I grew up in the foothills and I miss real mountains. Oceans don't have the same draw for me.
