That was the last year that you could get shrooms on the cheeky cheeky in the curio shops too. I remember staring at a puddle in hysterics as a group of people in tuxedos and wedding dresses filed past....was probably there for 2 minutes, but felt like a week.
Hopefully you've had all your bad luck!
