I think that the London suburbs are better for day game than central London is. I have done some daygame in the suburbs like Kingston and Hounslow But found that out there it is far harder to find women to approach. When I used to live way out at New Addington many years ago I used to go to Croydon and Bromely mostly to do day game. But it sometimes took me several trips to those towns before I found a woman there that I liked enough to approach. Back then I mostly approached women in shops and libraries. As it was hard to do street game there as there were only a few major busy streets.
