This cache is being placed in association with the NoVA Chapter of the Military Association of GeoCachers (MAGC) event held nearby on the date that this is published. You're looking for a micro sized container inside a host and you will need your own writing instrument to sign the log. You will also very likely need a TOTT to extract the log.
Parking is available very close to GZ and you'll be walking down a short gentle slope to get to the cache. It is also accessible a few steps from a paved path, so stealth will be required as passersby and drivers will be in view. It could be a fairly quick find for many geocachers once you get to GZ, but I wouldn't say that it's easy. It might take a bit of searching to find it. It is available 24/7, but be alert and careful if caching at night. I recommend looking for this during daylight hours only.
If you haven't found the other caches in the MAGC series, they are all fairly close by so I hope you take the time to check them out.
