Success in training the boy depends largely on the Scoutmaster's own personal example.
That's the way I like it because there's no time to have nerves about it. You just run out and do it.
I use something that is a real staple in the directing world. It's called a dance floor. You lay it down so that it's so smooth you can roll around, and you can put furniture on top of it. It's seamless and you don't see it.
