Ken Burns' Vietnam resumes

With the Vietnam series resuming tonight, I'm thinking, is it worth it? Worth the sobering sadness of continuing with the series.

I say, "You ready to go to Vietnam?"

He laughs as though he's read my thought.

Oh yes, it's worth it, Tommy Lee Jones says, with a touch of irony.

Bill just replies to me, with a twisted smile, "If you're strong enough."

It's good to start with a laugh, or at least a smile.
