qwazse, funny thing is, when I was a scout, I paid a little more attention to the guys with the silver knots, and that's the only knot that really matters to me. For those who proudly wear the knots in colors and combinations I never knew existed, I say they are fine exampes of the scouting spirit! I am impressed.
You are dead on with the hats to protect from the sun and the rain (and in my Pack, the occasional cream-pie!). In my day, we wore the red berets and/or the red and green ball caps. My everyday headgear now that I'm a Cubmaster is an olive drab boonie hat from the Army/Navy and I'm proud to say it is well-weathered and time-tested. I plan to wear my campaign hat for more formal or special occasions.
