When I was 15 y.o. and without telling my parents, I left from my hometown to see the F1 GP in Monza. Too bad that I went with my small moped, that had a maximum speed of 30 Km/h (it was the only one that my Mom agreed to buy me, because she was afraid of speed!), and my home was 70 Km afar. Once there, I tied the moped to a pole, and searched for the hole in the fencing that allowed to go inside without a ticket... when I came back, I realized that someone had stolen the tax disc from my moped... Indeed there are some things you remember forever.
