Well girlie, i feel your pain. I know where you are coming from when you say you get tired of being the only girl in a group of guys. That's how my world is and that's how i like it also. I get treated with more respect by the guys and they take my racing serious. I've always had the problems with girls being my friend because once they find out that mostly all my friends are guys, but just hang out with me to get a piece of them. Then once they get it....they leave me.
Sounds like you know what you want with your own chick racer group and I say go for it. I would love to start one up with you, but i'm all the way out here in Maryland and my sponsors are taking up all my free time. I say you do it for all the girls out there. BTW, a few of my close girlfriends made an all female (well there are just a handful of guys) but we have our own site and forum and we are a pretty close group of girls. You should check it out...

Well good luck girl...
