Rivka, I actually also always thought about Lana as blonde, but although in LNC (in Tempus Anyone?) she was presented as blonde, in Superman III she had brown hair. So I'm don't know which is right.
And if you are wondering why I'm on the boards all the time, well, what is a 15 year old with a computer in her room supposed to do on a saturday when she has nothing to do? I find this thread interesting. That and listening to the Lion king soundtrack over and over again. Hakuna Matata, people.
