http://ballotpedia.org/wiki/index.php/2013_ballot_measuresNone of the currently certified measures particularly stand out but I think all the annual state ballot measures makes for an interesting thread topic in general and there's probably going to be another 15 or so measures that qualify for the Nov. 2013 ballot in the coming months.
(Note - All states allow for the state legislature to refer a measure to the ballot, even the ones in grey on that I&R law summary map in the link above:
