I drive by this busy intersection several times a week and always see this beautiful horse sculpture. The nearby apartment complex has changed names several times, but the sculpture is enduring.
Parking is adjacent, but I would hardly call this a Park-N-Grab since you're looking for an itty bitty magnetic nano. This is a busy intersection, so stealth is a must so you don't draw attention to yourself. No climbing is required.
After you find it and sign the log, please re-roll the log carefully and insert it into the CAP first so that it does not get squished and bent out of shape.
