[Az-Geocaching] driveby geocaching

Just witnessed a driveby geocaching adventure. "The Kangaroo is Watching" is right outside our window. Although I didn't see them arrive, I noticed 2 people very quickly place our cache back into it's hiding spot. Almost out of nowhere a van pulled up, the door swung open, these two jumped in and the van took off... almost as a single rehearsed movement. I was quite impressed by the swiftness of these fellow geocachers :-)
