And so a small box truck, the kind that would be a food truck on Earth, settles in place at the corner of a park in a grey neighborhood close to the edges of a city in the slightly-less-dense areas. There's a subtle effect about it that should keep 'authorities' from noticing, without something prompting them, at least.
Nobody is in the truck's cab, but a short ramp leading to a door in the side folds open near the back, and a light-up sign declares 'The Wandering Store - Premium Groceries & Craft/Hobby Supplies'.
