You'll find a container at the posted coordinates. Inside, open "S1" to find directions to the Final.
This cache is being placed in association with the NoVA Chapter of the Military Association of GeoCachers (MAGC). We normally have a monthly event nearby, but those are on hold for the foreseeable future. If you are looking for a multicache that doesn't take long, this should meet your needs. Of course, you need to sign the log in order to claim it as "Found". Be sure to bring your own writing instrument. There is some room for swag and TB's.
It is available 24/7 and parking is available right next to GZ. You'll be partly screened from muggles, but be stealthy because it is close to a busy road and sidewalk.
I hope you enjoy this cache. If you haven't found the others in the MAGC series, they are all fairly close by so please take the time to check them out.
