Here's my pick for name & mission:
Name: Baby, You Can Drive My Car
Mission: To take long road trips to the next cache you drop me in.
Description: While I was in New York, I had a Rent-A-Car (Chevy Cobalt) where they gave me a double-set of keys. Since we went on a long road trip, I split the double-set into two sets of keys and gave one to my friend, so he could share the driving. Well, I forgot to give one of them back, and it has now become a travelbug!
