Fave festival was Guildford (UK) this summer. Especially staying up most of the night singing & drinking & chatting with the neighbouring tentfulls under the Welsh Widders' gazebo. My favourite memory is of running through the campsite to the loos several times at about 4am with Amoret (daughter) - both of us exhorting eachother to 'step high' amid gales of laughter (guy ropes dontchaknow).
Not very thoughtful for those trying to sleep - but I prefer to fool myself that our loud & lively little troupe was keeping the tent-robbers at bay.
