Thanks to all for the, erm, mostly nice comments.
With regards to theft (and not wanting to count chickens, owls or anything else), the only thing I've yet had stolen in Brazil was a laptop, in 1995, when I was actually at home in the UK. A work colleague picked up a PC virus during the Australian GP weekend, so asked if he could borrow mine for the season's South American leg. His hotel room was subsequently ransacked and my laptop disappeared in the maelstrom. Caution is advised - and I try to be as diligent as possible,
@new2me: I am privileged to attend all grands prix during the course of my work. Sticking a few snaps on here is less an exercise in exhibitionism, more a chance to let people see contemporary F1 cars that can be hard to capture from the public galleries. They are casual snapshots, no more and no less, and I make no claim to any kind of photographic prowess. I do the best I can with a limited range of kit (whatever I can squeeze in my hand luggage). If people like it, that's fine; if they don't, that's still fine.
@FranchiseJuan: yes, all taken with a K-5, mostly with a Sigma 100-300 f4 lens.
@Yvonne: I'm happy to accept the wildlife mission, although it is easier at some circuits than others. Somebody set me a similar challenge at Valencia in 2008, because they doubted I could find anything interesting against such an industrial backdrop. Five minutes later a kestrel flew into the media room window and remained for quite some time, stunned, on an adjacent terrace. The photos were a bit rubbish, though.
@Nigel: words are my profession, photography merely a hobby. In the circumstances, I'm probably unable to take up your thoughtful offer. Sorry.
Yrs twiddling his thumbs as yet another Porsche race winds to its conclusion,
