Unicycle
I just spent 90 minutes trying to learn how to ride a unicycle I bought on CL.
It was my first time ever trying one out but I had been wanting one for some time. At the end of the 90, I was able to traverse about 20-25 feet before bailing.
Not bad, I think. The session ended when an SUV with three teen girls blocked the path I was using to practice. Seriously made no sense. The ENTIRE parking lot was empty and they park in the one spot I was using. Oh well, I was getting hungry anyway.
