Update 5/25/2024.
The location of the cache has not been affected by the Big Remodeling.
It looks like, nature worked on the hiding spot and the cache has gone missing.
It has been replaced and is ready to be found.
The parking options also changed. You can park-and-grab the cache.
If you would like to take a longer walk, you may want to park at the Redmond Technology Station.
------------------------------------------------------------
The Seattle area has 100+ Microsoft buildings. The buildings on the Redmond campus are numbered sequentially except for the No. 7. There isn't one.
The missing building is a source of various employee pranks.
Perhaps the best known is when Microsoft managers send new hires to meetings in building No. 7, so that they can snicker while the new kid on the block scrambles to find the building.
Or another good one entails making an anonymous call to the new hire late in the day and telling them to report to building seven within 20 minutes to pick up a security badge.
While you won't find building 7 you might find something else.
The following signs can be challenging:
Unrestricted parking is available 20' from GZ.
The best way to approach GZ is from Bel-Red Road. Take NE 30TH ST to the GZ.
