There may be a few readers of this blog who are puzzle mavens but who are not Bay Area geocachers. If so, you may want to look in on a thread in the Geocachers of the Bay Area (GBA) forum. It’s a bit hard to explain, but a mysterious Russian figure calling himself Venona has emerged from his cold war socialist crypt to pose challenges to us stupid American capitalist morons. You may have to join the GBA, but it’s open to everyone and it’s free. Even if you don’t actively participate, it’s fun just to read through the thread and check back from time to time to see if the American morons have defeated Venona’s evil schemes. The link to the thread is below.
