Have other curious kids scared their parents when they discovered the Millrace?

I gave my mother a scare when at age four I took myself down to the Millrace--we were renting a house half a block away and I disappeared. She went looking, frantically,. When she found me sitting on the edge with my toes in the water, I was very impressed by her fright. Later on I went with my family to see the floats go down the Millrace, and that was lovely.
