I've not waited in a line like this for a good number of years, but then again, this is the first time in ages that I got to my polling place shortly after it opened.
I'll be curious to see how long the line becomes a few hours from now. (I don't live far from my polling place.) On mid-election day morning of 2008, the line extended outside my polling place, down the road near its entrance. I've not seen anything like that since.
