As a kilt-wearing hetero. man who is excited about both my favorite concert festival and the prospect of a 'kilt night', I'm a bit dismayed at some of the strong opinions against it.
To me PP is about finding others who share your passions and interests - whether it's prog, or power, or gourmet beers, or parts of the world, or some old band you wore the shirt of and you have a chat with a total stranger about 'the good old days' (the 80's!).
The kilt is just another expression. It doesn't impact our love of the music or the reason we're there... it's just another facet of my personality (freedom from the tyranny of the pant!) and I look forward to running into other metal brothers who enjoy the freedom as well.
Me and my tan, original Utilikilt will be there. Corsetted women, beware!
