This is no ordinary geocaching trading item!

Macra TB is a Travel Bug Dog Tag Travel Bug, traveling from geocache to geocache on a very specific mission.

If you do not intend to log your visit on the Geocaching.com web site, please DO NOT TAKE THIS ITEM. Its travels and its progress requires you to log that it is being taken from this geocache. You will also need to log when you place it in another geocache. It's easy!

If you are willing to log your part of this Trackable's journey and place it in another geocache as soon as possible (after you log your find), grab it from this geocache.

My Current Goal:

The Macra originated in our cache "Doctor Who - Gridlock".

It's aim is to travel to London, on the way collecting photos with as many Doctors as possible, if possible one of The Doctors.... 
This TB is on a race to London, though most of the other trackables it's racing against haven't been activated yet - this one gets a head start.  It's the third one to get activated.
