This final note today, my nod to the passing of Neil Armstrong, since I'm kind of a space geek.

There's nothing especially Marketplace-y about a 40-year-old moon mission. Except this: I read today that Armstrong -- and all the other Apollo astronauts -- got per diem during their trips to the moon. Eight bucks a day. Minus a deduction for accommodations, since they had the spacecraft to stay in.
