Just off the weeji board to my mummy, she agrees with you.
But she also said to check your blood pressure, and when a cruel big boy suggests its not that smart to ride by yourself with a joke helmet and gopro (which are banned from competition here after Shumaker's accident) you over reacted just a tad.

In this case, nowhere to go, and no one to practice with, I think this is the best option. The CCMCC usually have ideal entry sections, and friendly people.
