I've placed the third in my series of caches located at the center of a Zip code. It's called 30044 and will contain a Jeep TB and a Geo-Coin. (Coin courtesy of J. Johnston, 1/2 of YJJohnston, who helped me a little on the cache placement tonight)

The other two Zip code caches are 30045 (the first one I placed, which is my Zip code), and 30017 (just approved this morning).

There will be more in the series to follow. So far only one in the series is a Micro, and I'd like to keep it that way, but it might not be possible in some locations.
