Don't trust your GPS when downtown; use the Geocache map view or pin the coordinates on Google Earth before attempting to find this cache.
This cache has been Muggled a few times; so we made it a bit harder to find. Once you find GZ (the hint will help), you may have to find it by feel. You're looking for a magnetic nano, so bring your own writing stick. Please sign your initials only, no need to add the date.
Please rehide this exactly where you found it.
