Just to muddy the waters a bit, the summer camps in Northern California are in the High Sierras. The lakes consist of near freezing cold water, even in late summer, from all of the snow runoff. The question is whether a scout is, or should be, permitted to wear a light wet suit just to keep warm?
Understandably, it will provide some buoyancy, which may discount the effort in someone's view. On the other hand, it makes for a "safer" swim as the scout is less likely to experience cramping or severe loss of body heat because of the frigid temperature. NOTE: The surface temperature at the varies lakes average between 50-55 degrees in the spring and to 70 degrees in mid-summer.
I’m in a similar boat to you. For our meetings, I’m the first one there and the last one out (6pm to 8:30/8:45pm every Thursday). I do most of the planning as well. I try to do a camping trip once a month. (Keep in mind we only have 3 scouts right now). We have a committee meeting once a month and an charter organization meeting usually once a month. All this and still not counting the many other things that pop up. It’s a commitment but I enjoy every minute of it.
When I take groups on day hikes or backpacking, if their preparedness is unknown I start with some 'creampuffs' and then progress toward the real deal. I confess that I was greatly heartened a couple of years ago when I overheard one of the hikers on the phone to mom, "Mom, I just got my ass kicked by a 67-year-old heart patient". Right on! They did just fine after that.
