Mystery Hunt 2008 is over.
This year I had to hunt from Berkeley due to thesis pressures by keeping in touch via AIM and Skype. Staying awake for a long time to work is much harder when nobody else is around to help keep the energy up. But sleeping 3 hours in your own bed is about four times as rejuvenating as sleeping 3 hours on a couch or floor.
Just one observation for now : infinitely ascending chains of cryptic crosswords with interchangeable clues are awesome. But try not to pay attention to them when they start talking to you.
