Danny Messer riding a Harley on the FDR?

I was driving northbound on the FDR yesterday (Oct 5 2008)at around 5:30pm when we see a police car driving slower than the speed limit with flashing lights followed by a truck that looked like it was shooting a movie/show. The driver of the harley trailing the truck seemed to look like Danny Messer from CSI:NY.

I was just wondering if anyone can confirm they were shooting in that area or if anything like that is scheduled to be in a future episode.

I only found one little blurb about it in an interview that he did where he mentions that he'll be riding his harley ( http://community.tvguide.com/blog-entryy/T­V-S­how­-Bl­og/­T..­.72­5 )
