If you voted early this election (in person or by mail) and want to know if your vote was documented, you can go to the Secretary of State website to see if your absentee ballot was logged in, and the date received. Make sure it says "Absentee Ballot Received" for the date you voted.
I just voted today and mine is already in the system.
If anyone needs information on the referendum questions (other than school uniform question since we wore out that topic in the comments to a previous entry), ballotpedia is the best source I found.
If anyone needs to know where to vote anywhere in the US, Google has the answer.
