Chat em up at the supermarket, check out a sports/karaoke bar or a lounge, look up r&b / jazz or older type events where women that age are likely to pop out, or just be direct wherever you see em....
Older women love to be chased n feel youthful again, ESPECIALLY if she don't got a husband or man she's involved with. Almost too easy but you have to establish you're just a fun time by doing heavy flirting, showing intelligence/maturity can help but don't be overbearing, you wanna be her fountain of youth.
