1. I drive us up to the Ibis Hotel in Nottingham on Friday evening. 39.20 GBP for a twin room (20 quid each for sharers that can't do division, and you have 10 from not playing FNM). Get up at a civilized hour and drive 20 mins to the site in Nuthall.
2. Convene in Pimlico (Victoria?) at 7am or (probably) even earlier. I drive us up and back in the day.
3. Get the 07:30 train from St. Pancras to Nottingham and get a cab/bus the 20 minutes to the site. There's also an 08:15 train but that is almost certainly cutting it too fine.
4. Don't go :)
