Welcome to Colorado Karting Highlander!
You can see the assigned number plates in TAG Masters here: http://www.coloradosprintchampionship.com/06pointswithdrops/2006pointswithdrops.htm
The driver/racer license situation was discussed in a town meeting a couple of weeks ago. There was no conclusion at that time. Just log as much seat time as possible this winter, and get out there with as much on-track traffic as possible. Your times will drop and your skills will increase as you learn how to pick off slower karts, safely.
Don’t worry about your suit creeping up your leg while driving. That’s the first thing to creep up on you while driving. Just wait till you meet Mr. Jansen. 😯
Feel free to ask any question you please on this forum. There are many great karters out here willing to help you figure things out.
