Tops - what do you do?

Thinking about the possible return of spring and the also possible
return of my roadster, I'm curious about what you all do about tops 
when you park the car.  Do you leave the car uncovered, use a tonneau, 
or put the top up?  When I had a Fiat, the answer was easy.  I'm 
curious how others with not-so-easy tops handle this.  Does a tonneau
provide sufficient protection from a good thundershower, for example?
