Another random childhood memoy just came to me.
I have this vague recollection of my folks having a book which was, essentially, a combination McDonald's History, as well as a McDonald's travel guide (specifically, the locations of every McDonalds in Canada and, I think, the United States). I remember trying to read it again and again and again, because I figured this book must somehow be as wonderful as the restaurant, but I simply couldn't push my way through the dry prose detailing the rise of the franchise.
Coinciding with this memory is the realization that my parents, when planning our vacation itinerary, must've made every effort possible to ensure that there would be sufficient McDonald's stops along the way, to keep us kids satisfied (and coated in a glistening sheen of grease).
I'd be totally creeped by a similar sort of marketing move if I encountered it today, but as a memory, it still manages a warm place in my heart.
