Gardener - you asked: "I don't drink, don't like bars and besides I don't think that women in my age bracket are in the bars and I probably wouldn't like the ones who are.**Ladies: Where are the 40-50 year old women to be found?**"
Answer - dance classes. Find yourself a salsa, swing, or ballroom dance class and you'll be surrounded by women in your age group. Also you will be in the minority, there are always 4 women to each man in dance communities. It is also great GAL, great exercise, great social networking, and just plain fun. If you like it and become proficient at dancing, you will be able to step in to a dance anywhere you go and be a sought after man (for dances at least...but that can always be the catalyst for more!)
