x3. You'll have enough trouble worrying about where the actual starting line is, keeping the window up and the face shield down, where the turn off is, and what gear you're in before, during, and after the burnout... Keep it light, keep it fun, and don't expect to set records. My very first run I made 1/2 blind because I put my helmet on just as I was being waived into the box and I couldnt figure out how to get my glasses back on. Plus, I was paried with a 9 second car, so I could see the wall, but I couldnt see the cones or the stripes...lol. It was a great day, but a lot of basic learning to be done.
