Which do you prefer for a tripping venue, lakes or rivers?

Although I much prefer rivers for day trips I favor lake travel for
multi-day outings. Maybe it's the ability to base camp and day paddle,
maybe it's the (usually) more open vistas, maybe it's that I get some
peverse pleasure out of paddling in the wind at times. Maybe it's some
combination of things I can't quite put my finger on.

I'll have to ask the Missus; she *much* prefers river tripping under
any circumstance.
