This cache is NOT at the posted coordinates.
The listed coordinates are to a parking deck that is central to the walking tour in this series.
It should be noted that the Bonus Cache and the Adventure Lab Stages are at best a D/T of 1.5/1.5, the D/T listing here is due to the need to complete the 5 Stage Adventure Lab before finding this cache.
To get the final coordinates you must complete my Adventure Lab - A Cup of Civil Rights.
Just download the Geocaching Adventure Lab app on your phone.
The coordinates for the bonus cache are: N 36° 04.ABC W 79° 47.CDE (The number for "C" is used twice)
