When we were kids Perseus, Fanta (my brother) and I would hold regular Hotwheels/Matchbox Car race meets. Various tournaments would take place on varying tracks with varying importance. Sometimes it would be on orange plastic Hotwheels brand tracks, at other times we would use PVC pipes which we found lying around in the backyard, or planks of wood or even custom built tracks which had built-in (although not entirely deliberate) handicaps. Occasionally we would measure the furthest jumper or the fastest in individual time trials, but usually it was races of between 4 and 6 cars at a time, culminating, after several hours, in a grand final of the 4 fastest.
We had around a hundred cars each, we would relegate and promote them to the various tournaments based on their recent results and long term averages and we would draw up complex fixtures based on rankings. Each car had a name, the top cars were highly prized and stored carefully between races, while slow cars would regularly be thrown in disgust. We would argue over results (we alternated the roles of starter, judge and scorer) and would rotate the venue to eliminate home track advantage.
It was some of the best fun I ever had as a kid and, given that nobody else could be arsed posting anything, I thought I would reminisce in front of you.
