I had the opportunity (gag) to see Lady Bush, which I did take up for the photographic experience. My system was limited back in September, so I just used a Maxxum 70 Date with standard 28-100 lens. I couldn't get any closeups, except when she came around for handshakes, but I did get excellent shots. The guys at the pro shop were amazed it came from a just a camera like that (and they made some real nice high gloss prints of it) I'll post one or two if you want.
BUT ANYWAY, heh, I also had a very high power flash coupled with Fuji Superia 800 film. They looked great, but a flash is only good for such a distance. I would recommend a longer lens, but keep the 800 film unless you want anything bigger than an 8x12 reprint. And, run like a madman and push your way through the line - but not too obviously or Secret Service will own you!
Sorry for the short post, I'm off to school, I'll post more if I think about it.
