Hi Jules
Glad to hear about your mate enjoying the story :)
We were back on Expo last year, and will be there again this year, and I have to report that the toilet facilities there last year were absolutely first class, the women there kept them spotless, they did a fantastic job. Oh and they are portaloo blocks now, so no long drops !
Now I think about it, in the years since the unfortunate episode, we have camped at various places, Annex, Technopark etc and the general standard of facilities is actually pretty good. I must just have been in the wrong place at the wrong time under the wrong circumstances back in '98 :)
