Roller Derby Queen

I'm not sure if its my love of fishnets and stage names or just the need to set a goal that has nothing to do with mileage, time or the scale.  The Long Island Roller Rebels hold try outs in November.  This is perfect - just about the time MTB season is winding down and I should be a lot smaller ~ I mean stronger ~ by then.  My only knowledge of the roller derby is the Jim Croce song Roller Derby Queen.  I think I could be really good it for a variety of reasons...the most important that I love to skate ~ er.... used to when I was 10 ~ and that I think dressing up with a stage name and not having to shimmy up and down a pole is super cool.
If there are any Derby Ladies out there than can give me some advice please comment!
I'll keep you all posted on my progress - Step 1 - buy skates....
