If you want to meet a guy at church I have noticed some girls church hop to make room for options and go to all the stuff they do through the week, even if it sounds lame like a bake sale, just go see who is there cause everybody likes food.
Standing around outside a church looking alone and easy to talk to has to be the easiest place on earth to meet somebody, but if you are too cool for that then close your eyes and ask your heart where the person you want would hang out or is and go there because 70% of Americans are Christians and most guys are easy so if you are not meeting any you are likely hanging around negative places or not meeting enough people.
