The spouse has a tandem that's a bit too small for him, and a lot too small for me. We've only ridden on it once, and I was surprised how much I enjoyed it. Yes, there's a view of his back (he's a chunk taller than I am), but I liked the fact that I could look around and actually quite liked giving up control. He takes blind riders on the back, which means he's an excellent captain -- considerate, giving plenty of warning of what he's doing.

I have this dream of getting a tandem that fits both of us, but he's leaning more toward shorter city rides (mostly on his recumbent), and leaving me to do the long out-of-town ones alone or with friends. Last year was a funny one for biking - we were living in temporary accommodation and he was working on the new house we moved into in December, so neither of us rode that much. But right now his work has slowed hugely, so maybe things will be different.
