I agree with knocking on the door also. Yes I had more then enough doors closed on me but you know what after awhile I did not even care. I would knock on doors all day and after awhile you even laugh at some people. When I was knocking on doors all over southern Ontario I kid you not I had some strange experiences because you meet all types.
If I go out next week I will knock on any door as long as I don't see toys or play sets (hint) young parents I don't want to waste my time.
