Sex with older women?

hello I am a 21 year old male and i have had a fantasy about having sex with a significantly older woman for a very long time , I was wondering if anyone out there had tips or advice to help me meet with older women who were interested in meting younger men for a sexual relationship ? I know there may be a possibility with websites like craigslist and such but i would love to attend event where i could meet a matured woman in person . I am a californian just in case there are any events in particular i may be able to look into in my area but nay tips or recommendations are greatly appreciated .
