Myself and friends have had great success meeting technical folks and candidates for co-founders at networking events such as Start-up Weekends (http://startupweekend.org/) and local networking events you find through www.meetup.com such as Hackers and founders, Startup Meetup, Minnesota Entrepreneurs (Check within your state). If you are unable to network at events like this there are other avenues such as co-working space (In MN we have - http://cocomsp.com/locations/minneapolis/, Startup Loft - http://www.svl.mn/ etc) Good luck.
