Due to popular demand (well, two other people thought it was a good idea) I'm going to try and organise a fly in to Sywell later in the summer. See the BHX Bash thread on the Bashes Forum for more details, but in brief:
Sywell is all grass, with a lovely bar, hotel and restaurant. Around £50 for a double room, but I'll look into the possibility of camping. Everyone would be required to wear Biggles-style fancy dress too
