This cache was part of the series set out to support the 2012 Los Banos Geocaching Event, GC3RMVY. For that rally, each cache had a stamp to use in the tally sheet as well as a card that answered a question. Participants got raffle ticket(s) for each correct stamp/answer.
For post rally finders, it is all just the fun of the find for you. Come back in October for the next version of the rally fun!
