Well, after some consideration, it will be either Denham or (probably) White Waltham.
Just to make things more difficult I am planning to cycle from Fulham/Chelsea to my chosen field... White Waltham is doable (Thames path) as is Denham (Grand Union Canal towpath!!).
Must admit I havent seen too many happy faces at White Waltham yet... maybe they are waiting for me to flash the plastic or maybe the ride from London made me look a bit scary...

By the way the Chickenhawk name seems to have gone AWOL in the above pre-changeover post.
