This is part of a series of Traffic Light caches. The cache is
attached to some part of the traffic control system at this
location. Your mission is to find it. No additional hints –
besides the title – are offered.
As with most intersections, parking will be
“limited” at best. Expect to park away from the GZ and
walk in.
BTW: You are looking for a nano. Initials only on the log.
BYOP.
