I have taken the beginner and advanced MSF courses. I was in Alaska at the time. we were told that when we come to a stop, left foot down, right foot covering brake, keep it in first, and pay attention to behind you. this is what I do almost all of the time. there have been exceptions. they made sure to tell us not to take it out of gear for fear you might need to make a quick getaway. I'm right handed, but for some reason it feels more natural for me to put my left foot down.
