Trikes!! I had forgotten about those evil death machines! I rode on through a chook shed (chicken coup) once as a kid, trying to steer it....
I rode them quite bit as well in my late teens, to this day I still hesitate putting my foot down when's turning in on a dirt bike!
I've been having fun lately with my 1984 Tecate. I always wanted one, and I found an incredibly original, low-hours example in Bethlehem, PA this year. The pic doesn't show it, but it's just too nice to actually ride. It's more of a garage curiosity that I take around the yard occasionally than something I will ever take on real rides. A piece of history!
