Thanks for all the replies and suggestions. On reflection,it seems strange to be asking about activities in East Anglia since that's where I grew up, (hence my writing 'Fenland').
Slightly off thread, but then it's mine anyway, if anyone needs to know about folk in the Thames Valley/West London visit The Broadsheet
This is a blatant excuse to test making a Blue Clicky, (Thanks Joe for the pm advice, appreciated.)
