Erm, sorry, still trying to sort it; May is a busy month for me (lots of family stuff going on) so haven't had much time to do the research and make a decision.
Have had four locations in mind around the Birmingham area, however The Big Cycle Weekend in Derby looks interesting - especially as it's an already organised event that we could gate crash.
Google mapping shows its a decent sized park and the train station isn't too far away by the look of things.
I'll do my best to make a decision in the next week or so.
Cheers,
Shaun
PS. Hilldodger, can you send me a bit of bumphf on The Big Cycle Weekend - thanks.
