Spontaneity: the release from perceived boundaries and constraints.
I will note that in the past 5 days I’ve ultimately combed Boston over (as much as you can in 5 days) and feel as though I’m aware of most of the Boston hacks. If you go again it’ll be more intense. Still, the ridiculousness of exploring a city you have no clue about greatly contributes to ones feeling of adventure.
Still, it is far better for the subject to speak for itself than for you to speak for it.
