"Sounds good, I think there's a park in that direction," Terrence said with a grin. "Maybe half a mile away? Hopefully we'll find some good ones there."
He knew more about where Muggles went than he would ever admit to the head of the DMLE, but knowing the geography of this area was normal. Of course, Terrence was fairly decent at finding his way around London in general, on intuition rather than by a map or directions. There was no need for those when he could just Apparate to a known location if he got lost.
And of course, most of his detours into the Muggle world involved pubs and warehouses. A pub might work well, though getting a whole bunch of Muggles away from their drinks might cause more problems than strictly necessary. "Park works, yeah? We can Imperius a couple at a time, paint 'em, and set 'em loose for the hunt. Might want to set up a parameter to keep them from running too far, at least until we're a bit more used to our weapons."
