One thing about flying, you almost never notice bugs or insects of any kind in the cabin.
But you can't be too careful.
So I like to sit next to someone like this guy, my row-mate on an Air Canada flight last year.
This was duly noted in responses to my Seatmate Questionnaire....I'm posting this mostly for the benefit of my sometimes co-blogger Crosscheck, who abhors the public sleeper – and most of all the gape-jawed public sleeper, like this dude.
