Wheels On. Unfortunately for them, I have no skills when it comes to building so they are very limited in what we can do. I tend to get irritated by the dad that won't even let the kid touch the car because the dad obviously did the whole thing.
The crazy thing is there have been some years when I was hopeful they would be close in at least one race and yet those years their ugly cars somehow beat the professional looking ones.
There seems to be no rhyme or reason to the thing. I know for me it is all about the time with my boys as we build. Although the last couple of years I have had to build a princess car for my two little girls, fortunately for me they don't care that it is the wedge shape (my most proficient cut) they just care about the color 😁.
