i did try this back in the summer.
she was mowing her front lawn, so i just pretended i was spraying my weeds and then went up to her and said "hey don't think we've met before", and then just see what happened.
turns out she was into football etc, so was quite an easy conversation. but it wasn't one i felt comfortable trying to close.
it's a bit of a tricky one though, there is a saying "don't shit on your doorstep" that is there for a reason.
