Travelling socks

I have been working on the travelling socks - while travelling. I think about 3 or 4 more rounds on each one - then I can start decreasing for the toes. I am using the pattern from Nancy Bush's Knitting on the Road book. I think I made the legs a little longer than the pattern called for. I was surprised by the toe pattern: not having read all the way through the pattern, I didn't realize that it calls for a decrease on each of four needles up to the end, rather than the usual paired decreases on top and bottom. I can put off the decision of whether or not to deviate from the printed pattern for a few more rounds, then will have to decide!
