I suspected that Norwich would be a problem - I'm painfully aware of the difficulties involved in getting in and out of the city!
I shall continue to explore other, most westerly, options - focusing first on Cambridge and then on Peterborough. If you know of any good venues in either city, please let me know. A well-known Imperial War Museum has just quoted me £750.00 for room hire, so I'm concentrating on game stores and scout huts!
I offered to help arrange Blog-Con3 because of the real possibility that it wouldn't happen otherwise. I'm based in the East of England and it's not practical for me to try and plan something further afield. However, Blog-Con is a movable feast. If you have ideas of good venues in the midlands, south west or anywhere else, save them up - they may come in useful for Blog-Con4 or 5!
So the next question:-
Would you attend in Cambridge?
Bring & Buy/Swop-Shop
This would depend on the venue - if a shop, I imagine they wouldn't be too keen...
