To relocate the scent, good hounds will run a zigzag, sweeping wide left and right until they pick it up again. I tried this on a street near my office, after a young man passed by in a reek of Axe body spray. I let him turn the corner and disappear from view, then waited a few minutes. By zigzagging hound dog-style, I was able to track him to his destination, a cheesesteak place on the next block.
