Zac you bring up many good points. As you said judging with your friends cars even if you try to be unbias will still be bias because subconsciously you’ll be influenced either by knowing more of the small details of the car since you’re familiar with it or favoring it since you know the person. That really is something that is tough to deal with when judging.
Moreover, as you said judging turns it into a hectic job of finding where cars are and actually judging them. I love coming to shows because its so relaxing and I can just enjoy the day. Judging would take the fun out of it for me.
