It went pretty smoothly--M got in line at 5:45 a.m., I joined him at 5:52 (running a tad late!), the polls opened at 6:00 a.m., and we were finished at 6:38. Getting there at 5:45 was key, though--when I showed up, just 7 minutes later, there were at least 50 people behind M. We were probably about 80-100 people back from the start of the line.
Here's the line at about 6:05.
