I've been given 90 days of solitary writing time and I get to choose where I spend them (this is one of my favorite fantasies, so humor me.)
Here's how my dream would go... I'd get paddled out to a tiny island carrying a laptop that operates on solar power. I'd be wearing sandals and island attire that would stay clean and unwrinkled the entire time I'm there (again, humor me; if I'm allowed to choose where I do this writing stint, I figure I'll drop kick a few other realities onto the other side of logic too.)
I'd bring a hammock, and my meals (including shots of espresso) would be delivered by the nice man who paddled me over to my tiny island. There'd be no phone, no family, no pets. Just me and the story for 90 days. This might not be everyone's heaven on earth, but it'd be mine -- just once. And no, you can't come with me. Find your own tiny island!
