picket line

His father brought him to a picket line when he was six years old.

Everybody went home an, we were all on picket line after.

But have we ever seen him on a picket line?

Some have been up since 12am to man picket lines.

She could see the picket lines off to the right.

To my knowledge there was never even a picket line.

And I know full well now what it's like to be standing on a picket line for seven months.

Came through that picket line in the dark and all.

I still can't quite believe I'm out here on a picket line.

Did you not state let them fight it out on the picket line?
