I voted at about 9am in Ann Arbor. The poll workers wouldn't tell me if the Dems had delegates or not (I asked to see if I could tell Dems to ask them). There were sample ballots so you could see Obama and Edwards were missing on the Dem ballot. Ron Paul was listed 1st on the R ballot.
My polling place has two precincts at it and typically the most voters of any polling place in Ann Arbor. It is also almost entirely Dem, and the Iraq war is a big issue. So, from 11 to 2 I stood outside the polling place with a homemade sign saying "Bring Our Troops Home Now. Vote Ron Paul Republican. Notes: The Democrats don't have any delegates. Obama and Edwards aren't on the ballot. Ensure two anti-war cnadidates in November: Vote Ron Paul." I got at least two people to vote for me (one talked with me about it beforehand, the other gave no indication he had seen me until he walked by and said, "Well, I did it. That's the first Republican I've voted for since Reagan.") I also made friends with the two women collecting signitures (one for a Michigan constitutional ammendment for universal healthcare, the other to get Rep. John Dingell on the August primary ballot).
Anyway, I had to come home to be with our three young kids so my wife could go to work. I stuck my sign in the ground so it can keep speaking, though.
