Here's one of my blogs about my experience: http://nadinebrandes.com/2013/08/21/whats-your-adventure/
Competed as a boardercross racer for a year. Went to the USASA National Championships and placed 13th. Overall, in my class, I placed 7th/53 women.
Never raced before this year. It was quite the experience! As exciting as it was for my husband and I to road trip to the different races and learn the ins and outs of being a racer, I'm happy it's over. My nerves and queasy stomach weren't made for racing. Still--awesome experience!!!
Buy a good helmet! LOL.
