Walking Through the Mall - Solution
by
Erik Oosterwal
This same kind of puzzle finds its way into most puzzle books and magazines
from time to time. The solution is not completely different from
Trace the Circuit and
Trace the Circuit - Part 2 on
The Puzzle Page, except that this one doesn't
require you to stay on a grid, and there are fewer sets that need to be
connected. If you haven't tried them out yet and enjoyed this one,

As with the grid tracing problems, the key to solving this brain teaser is
realizing that Bill's path to his destination cuts the 'mall' into two parts
and everyone to his left has to stay to his left and everyone to his right
needs to stay to the right.
