This is a post I made in response to a similar thread in another forum:
Generally, I like Keillor. He's funny and "down home." But I think he's way off base here.
There are lots of ways one can "celebrate" (that word never quite fits with Memorial Day, but let it go), and I agree that visiting the National Gallery is one of them. It's not the only way, however, and to impugn the motives of those who choose another way is at best rude, and at worst, a cheap shot at a lot of veterans who, more than most, understand the meaning of Memorial Day.
Mr. Keillor can visit the National Gallery on any day of the year, and the meaning of the gallery will be the same. Visiting the Vietnam Wall on Memorial Day is, however, a special event on a special day. Going there next Tuesday would NOT be the same. So let those for whom Memorial Day is indeed a special day celebrate it in whatever way they choose.
Just a final note.... I'm sure that there are posers and wannabes riding in that crowd of veterans; that's their right. And I'm just as sure that there are poser and wannabe art afficienados hanging out at the National Gallery hoping to see and be seen.
