A fellow night owl friend of mine lives on the East coast and does remote work for a company on the West coast, during their normal business hours. I must admit to a bit of jealously.
I worked on a west coast based team in an east coast office for a while. It was pretty great until I had to work on a project on both coasts. I had calls scheduled anytime from 9am til 8pm.
I have the opposite spatial arrangement, and I'm honestly not sure how long I'm going to be able to keep it up. It can be a serious drag. Although I have rediscovered the glory of naptime.
