I physically found the cache and signed the log back on 26th November 2013, at which time I did not qualify. It has taken a little longer than anticipated but my recent trip to Florida finally provided an opportunity to nab something suitable - see my web page http://www.15ddv.me.uk/geo/chal/rubyshoos_challenges.html#48 for details of the qualifying cache. And so I now claim this challenge cache!
PS. In case you were wondering, yes I did meet Mickey and all his friends.
