The question about being careful during the convention is - I'm not really sure how to do that. A lot of time you think you're being careful and then something happens nearby and boom - people start panicking and shoving and things get out of hand. But you don't know where it is going to happen. I think the real danger is either a faux terrorist scare or a real one. Even a false scare could cause panic - and with the crowds on Sunday - I think that is the most dangerous day.
As far as pictures go - I don't see myself as a real photo-journalist - today, in fact my best pictures were taken on the way and on the way back from the garden (haven't posted them all yet). Maybe that's what I should do on Sunday: go down to the start of the protest, get out, look around - and go back home.
I think there were two sitcoms about photographers with this problem (Mary Tyler Moore Show and The Odd Couple). In the former episode, the film cameraman films ants trying to get out of the way of a fire. I think it was Lou's nephew.
On the Odd Couple - Felix is hired to photograph a boxing match and winds up with a shot of a fly on the bell which he says symbolizes something or other.
