From my unscientific research (just talking to people), it's a bunch of older folks, I believe mostly retired, that like to feel useful, and do all these service projects to that end.

Where do you get the "diabolic" aspect of things?

I'm already pissed at Rotary, because in a place I used to live, there was an outstanding playground for kids, that had some fun, adventurous equipment. Kids would line up for an opportunity to use their favorites equipment.

But the Rotary Club, "charitably", tore down this perfectly good playground and replaced it with a "differently abled" playground, which wouldn't entertain any kid over the age of 2.
