A simple offset multi cache where all you need do is park your car (use the parking co-ords listed below), walk to the listed co-ords, find the container hidden there, work out the final co-ords and head off to GZ to find the cache.  There are co-ords for the trailhead listed below as well.
Sound easy?  Good.  Hope you enjoy the hunt and short walk.
And to help you out, checksums for GZ are:
South 33Â & East 26
