I have a little bit of experience picking up quasi-famous women, but not anyone super famous, and not enough of it I'd feel comfortable writing a piece on it.
Alek may have had some relevant experience over the past year. I'll ask him.
As far as weddings, I haven't heard any of the guys mention those, no.
I've only been to a couple of weddings in my adult life, personally -- not sure what the case is for the other guys, but I think for a lot of cold approachers, you are dealing with bachelors who don't do a ton of normal social circle stuff, and whose friends are similar, so there's not a lot of weddings they find themselves attending (different in Eastern Europe, I realize... you're probably finding yourself at weddings fairly often).
