Im not a lady, (looks down), yup, definetely not a lady, so I obviously cant go, but Ive seen the ladies out on the snow before.
Its pretty cool actually and its great thing that they put on. If nothing else, it may bring more women to the sport and give them the confidence to not only ride, but to work on and even mod up their own machines, and as far as Im concerned thats a great thing.
I talked to a few of the ladies who were with the group (they were hot, blonde and rode sleds; what else do you expect a fella to do?) and they seemed like they really had fun on the ride. The ladies were laughing and joking with each other.
I think you will have fun on it. Make sure to take lots of pics and let us know how things go.
