I won't get into the pissing contest either, but I will say this: I think all series each have a different level of difficulty. I've read F1 drivers or any open wheelers that have said it's really tough to drive a stock car because it's so heavy and doesn't respond like what they're used to.
OTOH, I've read stock car drivers that have said open wheelers are hard to drive because they're light and flighty. Different strokes for different folks.
Every woman I've ever watched try to make a go at stock car racing has stunk it up. I don't like Danica at all. I think she's a snotty, stuck up little b****. I also don't think she has what it takes to drive a stock car. I'd love to see her try and fail miserably though.
Honestly, the only thing I ever cheer for women in at all....is drag racing. Don't know why, but that's how I've always felt about it. I think women's sports are booooorrring.
