This year's annual meeting in the American Oil Chemists Society was held in Phoenix, and that was my purpose for being here, but I also managed to squeeze in a bit of geocaching. On Saturday morning I took the Light Rail to Tempe and found a bunch of good caches, including this very interesting virtual cache, which was visited at 12:01. This by the way happened to become a mini milestone for us: Our find no. 7700.
Thanks for the quick permission to log and thanks for the cache!
