I shall also join the above posts in singing last night's praises. Best storm here for years, over an hour of frequent, incredibly bright lightning, as well as near constant thunder, not to mention the torrential downpours. Awesome.
Hopefully something similar occurs during the summer holidays so I can stay up and try and take some photos without worrying about being tired at school, although it will be a long time before anything like that happens here again.
I'm in Crete from 25th July-8th August though, be interested to see if anything happens then...
