Seems Mars has always stolen the thunder from Venus in the cultural imagination, because you can SEE the surface. People just assume Venus is always cloudy and thus there's no oppportunity for theories about lost civilizations.
There's also this small matter of Venus having an avg surface temp of roughly 400 deg celcius! I really doubt ANY civilization could've taken rot there, ever. Mars on the other hand, was once warmer and had water and a half-decent atmospheric covering. My vote is for mars to be further explored for signs of past life.

I was kinda kidding around, actually. :) Mars having "rocks and dirt" just made it seem a little more believable as a place where aliens ran around. Venus is the big soup, and there's little possibility of chase scenes there, Edgar Rice Burroughs notwithstanding.
