Well, that being said there are No Requirements or Obligation to complete this task before finding the cache. But, I would like to throw out there the challange of having a combined total of Favorite Votes for all of your owned caches to equal 100 or more. If you havn't hidden any caches come and get the Smiley anyway, no worries.
Bragging rights are OK. If you desire, it would be great if you give your current total in your log.
Our current total is 406.
Good Luck and Have Fun!
