York County, Adams County, Pennsylvania Astronomy The Scout Merit Badge Program

I stood and stared; the sky was lit,
The sky was stars all over it,
I stood, I knew not why,
Without a wish, without a will,
I stood upon that silent hill
And stared into the sky until
My eyes were blind with stars and still
I stared into the sky. --Ralph Hodgson (1913)
