I agree with Prisca:
Church clubs or local activities in your area.
Try volunteering at a local charity organization. I work at an agency and guys volunteer to carry surplus food out for the elderly people. I always think they are so sweet so do that on their own time. Lots of young ladies work in the offices too. This is very impressive! Also this may sound dumb but the grocery store is a total hot spot. I always try to go shopping with my husband because I cant get a gallon of milk without someone saying hello or making eye contact. There is always somthing to talk about. "Have you ever tried this"? etc. Some girls wont respond but dont worry, you dont want those girls anyway, eventually one will.
Be yourself and good luck!
P.S. Dont go to the grocery store every day, they will think you are a stalker. Oh, and always have somthing in your cart and buy it.
