One of my dads hobbies since retiring is Scalextric, he currently has a track built using pieces of Scalextric track, but he is now in the process of routering a track custom to what he wants.
Photos below are of him building his original track also of his collection of cars, sidecars, motorbikes, horses, trotters and some other novelties vehicles (Notice Mario cart and DK cart at front - thats the link to RGR ) Thought some fellow RGR's would appreciate this.
