Found this on the ground speak forum ... wonder if peeps in the AZ area will do this so that my bug can travel :)
Release Notes 7/28/10
Trackables Dipping! You can now "Visit" a trackable in a cache. This allows you to drop and retrieve a trackable in a single step. To dip a trackable it must be in your inventory. The cache logging page has also been redesigned slightly to make it easier to select the trackables you are dropping/visiting.
