TFR over NASCAR race was possibly violated, too

This past Sunday I had the opportunity to take my two children to my and
their first NASCAR stock car race at Watkins Glen, NY (USA).

As we were sitting in the bleachers listening to the Canadian National
Anthem just prior to the start of the race, I looked up and saw a Cessna
172 circling about 1,000 feet above the 200,000 spectators', teams', and
vendors' heads.

Conditions were marginal VFR and the 172 made three passes before leaving
the airspace.

In thinking about the official TFR in place for the event, I wondered if
this C172 pilot received a waiver to loiter over the event. Aerial
photography, perhaps?

Oh, and on an aviation related note, a B-17 and a B-25 performed two in-
formation fly-overs about two hours before the start of the race. Now
that was a sight to see.
