Agreed, you'd be mad to leave on Sunday night. Some of the best acts I've seen have been the last act at Pyramid on Sunday night.
I've never understood all those people who are in a desperate hurry to get away either Sunday night or the wee hours of Monday morning. Chill the f**k out and stay a bit! You've spent ridiculous amounts of money getting there and enjoying yourself, why the big hurry to get away?! First year I went my friend announced she hadn't taken the Tuesday off work so wanted to leave at 5am on Monday morning.

Not a chance and since I was only one of two drivers.. well let's just say we didn't leave at 5am! Last year we got up late, had a leisurely breakfast, cleaned the van and chilled out enjoying the sunshine until things had calmed down a bit. Took an hour or so getting out of the site and it was plain sailing after that.
