I've fortunately never had to do that as a result of circumstances Stu - tho I have done it through choice once! It wasa charity thing when I was at school, where you live like them for a day and a night and get sponsored for it, and the money goes to charity. Of course it weren't real - we were supervised, all had sleeping bags etc, and weren't really "on the streets" bla bla - but I do know how cold and miserable it can be, so I can sympathise(sp)
