I've no idea what they mean by "Free range bees!" The footpath runs through the grounds of a very large private house, and these notices are to discourage people from straying off the path. Last Easter, bunn ignored the warning and made a brief detour to examine a plant, and didn't return screaming in terror, chased by hordes of bees. I suspect they're a myth, perhaps to prevent walkers from discovering the secret spy base they have hidden in the shrubbery.
