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 a result, I am upping the difficulty rating some.
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. Please be sure to roll the log up tightly. It should be placed in the cap to minimize damage. Also, please close it tightly.
***Congratulations to GizmoBobo on their FTF***
