Backyard Roller Coasters and a Souped-Up Lightning McQueen – These Dads are Awesome![VIDEOS]

A dad is supposed to be a superhero to their kids.  Of course, they need to love, care and nurture their children, but some dads go above and beyond that for their kids.  Check out the videos of what these amazing dads did for their kids.

I must admit any dad who would build a roller coaster in their back yard for their kids has to be pretty special.

Or how about this dad that souped-up his kid's Lightning McQueen car.  As they say, "just fast enough to make it seem unsafe."
