Well I was driving through downtown and lo and behold I came across the Prison Break folks shooting a scene.

To be honest after I had shot most of my shots a member of there staff walked the 1/2 block plus and asked me to stop taking pictures, I was pretty much through anyway and said OK and walked off, no threat for the card or anything just a request to stop. Since it was on a public street and there were no barracades to cross the set could not be considered "closed" and not much he could do other than ask.
300mm 2.8 with a 2x tele on it and since the 300 is an older lens that is manual focus I actually was underexposing by about 1/2 a stop so the shots came out a bit grainier than I hoped for but still acceptable.
Heard that they have been shooting in the area already for a couple weeks, so this scene will probably be in the first or second show of the season.
