Scour the local meetups that look interesting and research the age of the group and the average attendance. Contact frequent attendees and query them. I'm in a large metro area so there are professional, hobby, social and sporting/outdoor groups of all types. I've met folks from hikers, body builders, travelers, sci-fi readers, robotics enthusiasts, radio operators to MSSQL DBAs.
