Picture this - a sky full of thunder

Attention grabbing:

kneeshooter, grahamb, davefish, grumblesmurf, wimble - we're just over half way through the time available for getting photos ready for the second photo challenge.

neilh, nalsa, brrm, failmaster, narenek - are any of you playing this time ?

Anyone else is welcome to join in too - instructions are here. As before, partial collections of photos (ie if you started, but then ran out of time/inspiration/patience) are also fine.
