Since the water has come out the back of some lorries I reckon they're hoping to grow some Leyland DAFfodils.
Here all week. No, really.

Tell a lie, Bottas has gone out in the Mercedes.
Three soggy laps on the extreme wets and he's back in.

A reminder that they gave re-watered the track at lunchtime.
So no-one is exactly rushing to get out there.
Who, what, where, when - the answerpublished at 13:00 Greenwich Mean Time 2 March 2017
Hello, hello.
We're back again so let's get straight to the answer, which - as many, many of you said - is Graham Hill surveying the wreckage of his Lotus 49B after the rear wing failed at Montjuic Park, 1969 Spanish Grand Prix.
I am - as always - humbled by your knowledge.

Right, time to rest a wee while. We'll reboot this page just before 13:00 GMT.
To tide you over, here's a lunchtime teaser of the Blurry Picture Quiz variety.
Normal rules apply. Simply tell us WHO is in this picture, WHERE is it, WHEN is it and WHAT is going on.

Session over.
Hard to sum that one up really.
Obviously there's been lots of lovely data harvested by Pirelli, but I'm not sure how much the teams would have got from it.

'We're happier than you would think'published at 11:53 Greenwich Mean Time 2 March 2017

F1 journalist in BarcelonaToro Rosso’s Technical Director James Key had a midday meeting with the media. Daniil Kvyat’s car is currently undergoing an engine change.
“When we have run, it has been OK,” Key said. “We have not had nearly as much running as we hoped for various reasons. We are stuck in the garage at the moment. So it has been a bit frustrating as well. We have only run the medium tyre, and we have not done any performance running. We are not doing lap times this week, we are just trying to get miles on the car.
“But everything we have seen in terms of the aero numbers, in terms of the characteristics of the car, appear to be pretty much in line with expectations. So on that basis we are actually happier than maybe externally you would think.”

Mercedes send out Bottaspublished at 11:52 Greenwich Mean Time 2 March 2017
Conveniently, the Mercedes has shaken off its electrical fault now the track is dry and is sending the W08 out.
Lewis Hamilton has already informed us he won't be having a drive today, so it's Valtteri Bottas - scheduled to take over the car this afternoon - who gets a pre-lunch outing.
