anything that gets their attention, I would guess too that most ask you how you learned to do that kind of work, that would be a great time to say in HS I made good grades, math was important because it allowed me to go to trade school/ college and that is what I took, yada yada, may not be true, but that would be my story, you know, how to do CAD design, etc. They see the bikes being built, they use computers to manufacture those parts, seems like a really good way to introduce them to that way of thinking.
