And I didn't even realize what was going on until MSNBC mentioned that people were still voting in Franklin and Knox counties in Ohio after midnight.  I think CNN and NPR reported on it as well.  I was confused - I had voted by absentee ballot, but everyone I talked to reported about 45 minutes-1 hour standing in line for voting.  I had no idea where in Knox County (which only has a population of about 50,000) this could be going on.

I found out about it the next day.  Students waited in line until 4:00 am to vote.  There was a crappy article in the local newspaper about how it was all just an unlucky confluence of events, blah blah blah - they said they had 2 polling stations open, but one worked very slow for about 3 hours until it was fixed.  It was a whole bunch of "Not our fault!!  This happens!"

Except Gambier (where Kenyon is located) is pretty much the only reliably liberal area in this county, and they were the ones to have this problem?  Also, in the months preceding, there was a scare campaign directed at the students to try and stop them from registering to vote in Ohio - telling them they could be committing a felony, etc.  The local Dems did their best to correct this disinformation, but enough crap has happened directed at Kenyon that the whole thing feels wrong to me.  Just like this whole election feels wrong to me.  :)

This is a good site that has tons of complaints (irregularities, appearances of malfeasance, suppression) logged next to states.

Maybe yours has not been logged.

Happened in Franklin County, OH. I was volunteering with Just Democracy at the OSU student union polling place, which covered the entire university (50k people, unsure how many registered voters), and I believe a few other precincts. Either two or three machines were provided. Early in the day, the line was somewhere between an hour and a half and two hours. Around 6 or 7, the line appeared to have doubled. I have no idea how long the people at the end of that line ended up having to wait, but I did see a number of people leaving because they didn't have the time or patience to wait. On the other hand, however, it was very encouraging to see so many of my fellow students giving a crap enough to wait so long in line to vote. I talked to one girl who had been given the run-around and sent to 4 different polling places (each polling place would tell her no, she was in the wrong place, go vote here), and was still trying, and a few people who waited in line for an hour and a half only to be told they were at the wrong place and they'd need to go wait another hour and a half to vote somewhere else.
I was surprised, though, that the county didn't send over some more machines or something. It seems like someone made the reasonable assumption that a lot of students, of all people, would not be willing to wait very long, and since they go overwhelmingly Democratic, this might be strategic. I'm not trying to be a conspiracy theorist, and I understand turnout has been incredibly low at the student union in the past, but it seems like the county should've been more prepared to alleviate long lines. This could be a bureaucratic oversight, or it could be that someone is in someone else's pocket.
That said, Just Democracy is nonpartisan, and man, was it hard to be nonpartisan for 3 hours.

Precinct 353 at the University of South Florida had the same exact thing happen.  I can't find the link to the article anymore and tbo.com took it down. But basically, the lines were so long with only 3 voting machines that they brought in a 4th at 3:30 pm. They also moved another of the campus precincts to a mobile home off to Skipper road and it was locked behind a chain link fence, alot of students had no way to get over there and if they were able to, met the locked fence. They also stated they weren't informed of the precinct change..of course, our Republican SOE said of course they were, the same guy who left a Democrat County Commission Candidate off a precinct's ballot. I wish I could find that link.
