It does look pretty. I've never been to Poland but one of my friends has and he said the architecture (or what was left of it I assume :S) was very pretty.

Also, electrical storm = really really cool. I love huge thunderstorms, especially the insane summer ones in the medeteranian. There was a small one when I was in Greece and I wanted to go jump about in it but I was just too damn knackered by that point. I swear, all I did on that holiday was sleep and arse about in the water ^_^
