It seems that annoying passenger behavior is the hot topic this week.
Here's your chance to chime in, by voting in the "Most Annoying" poll in the sidebar. I've culled the past posts and comments to gather a fairly extensive list, but I've still left room for "Other." If you do choose other, please take a moment to list your "most annoying" in the comment/discussion section of the poll.
I'll keep the poll open for a week, and then post results.
