I don't do this, but one of my friends is a devout runner. He says he actually does most of his pick-up when he is running around. He'll stop when he seems a hot girl and talk to her. I'd imagine that it makes his seduction very authentic. He also loves to go ultra direct, so that's probably pretty funny. This sweaty, jogger comes up and goes all direct and shit on you.
I will be checking my PMs weekly, so you can catch me there. I will not be posting.
