Hi Jason
Just wondering who or what group can I get in touch with to go mud larking? I will be in London June 29-July 2 and have always wanted to mud lark!! It would only be for one outing so getting a permit would be pointless. Hope there is such a group like that to take tourists out. The photos of your treasures are extraordinary!!
Thanks for any help you can give me.
