Photography in an English heatwave?

Here it comes again. 23 degress at a little past 6am. :) These are fine days, incredible colours given to us from nature that photoshop will never be able to replicate.
Let's get out there and enjoy folks. 31 degrees today and Murray is through to the semi-finals. Can he go all they way? We'll soon know. He's as cool as cucumber, I'll give him that, quite extraordinary, dealt with the wild card in straight sets.

And in this heat. A consumate professional. At last.
