A couple years ago while living in southern Italy on business every day I used to see this grey old man on a grey old Vespa with a white and tan old hound perched on his floorboards as he went to and from his field. Then one day I saw a black haired young man on a shiny new black Vespa with a black young hound and I thought "They have GOT to be realated!" Unfortunately I was never able to capture a picture of it!
I also remember seeing a couple with a toddler sanwiched in between...THAT had to be Safe! Anyway, from my time there ANYTHING can be carried on a Vespa! I always thought the helmet hook was a grocery bag carrier...that is all I ever saw it used for!
Surely pictures of someone like the late Giorgio Bettinelli would convince them that a determined person on a Vespa can do ANYTHING!
