Good advice. Go where you would hang out if you were a couple. And don't be afraid to ask friends (ones that you trust their judgment) about single women they know (after all they know something about the two of you and that at least gives you a fighting chance). Also volunteer is a good thing. Scout leaders (boy and girl), church youth groups - after all kids have moms (a lot single) and a lot have older sisters. Have fun!

PS. and the crossfire may attract a few when you park it at the park!
