Woodstock now as then is shaping up as one big media trip for Henry Diltz.

Diltz, rock photographer supreme and owner of the fine-art photography Morrison Hotel galleries, has been on the phone more times than he can remember in the past two months, bombarded with calls from Japanese magazines, German documentary filmmakers, and eight book authors. "Now, the newspapers are calling me," said Diltz, 70, who was the Woodstock Music and Art Fair's official photographer by way of his friend, lighting director Chip Monck, whom he knew from his days playing banjo on the college circuit around three years earlier.

Feelings of anticipation arose within as I crossed the threshold of a two-way mirrored pavilion, "Girl's Make-Up Room." It's one of Dan Graham's glass and perforated metal, large-scale pieces in the conceptual artist's first ever career encompassing show in the U.S., "Dan Graham: Beyond," which is up at the Whitney Museum of American Art. How would I see myself in the mirrored and metal reflective surfaces? How would I perceive other people? How would others see me?

Much as fashion and make-up afford ways in which people show themselves to the world -- and can be seen by others -- Graham's eye-popping sculpture-and-architecture as art tosses back images of one's self, images of others milling about the Whitney's expansive fourth floor gallery, and the occasional look at another visitor looking back at themselves in the pavilion's facade.

When two guys on the Lexington Avenue IRT start griping about how it's taking upward of $100 to fill up their SUVs, you know there's something going on out there. But when such concerns start rattling the nerves of Park Avenue millionaires, it prompts the question of exactly how far-reaching and long-lasting the growing threat to the country's prosperity might be.

Will wealthy Americans keep curtailing luxury spending into 2009, or will they be reaching back into the spending till, after a relatively brief pause? For how long can they resist the yacht charters, private jet miles and $200 Kobe beef burgers that not long ago would have been consumed at a whim?
