I just found this thread and thought I must contribute. Three ideas that work for me in Denver, CO:
Running Clubs. In Denver there are running clubs just about every night of the week. Do a 5k then mingle and approach girls.
Breweries. There are lots of microbreweries that throw events. Get on their mailing lists. Tons of girls standing around drinking craft beers. I like these events because they are not high pressure like a club, alcohol is involved and the girls I meet are laid back.
Adult softball, kickball leagues and ultimate frisbee leagues. Always a bar afterwards where you can talk etc.
