My vote is for tucked. When a Uniform is Untucked it looks sloppy, and disrespectful. As for wearing your class a in the field, WHY??? It is just stupid to wear your class a when doing work, it gives more possibility to getting the uniform dirty, another possible disrespect. I feel that the BSA is getting too soft and lax with their judgement on things like this. Whatever happened to the days when you just went out into the woods with only what you could fit into your pack, no trailers or any of that, and just camped and enjoyed nature? We should focus on getting back to the basics of scouting, in other words, look professional. Its a shirt, not a skirt, tuck it in.
