As a thin, attractive (not to be arrogant but I am) trek adoring lady do you think I would be mobbed at a convention by the thirsty fat shit neckbeards?  Of course you would.  Sure some people are interested in Trekdom, like myself, but there's a lot of people that really do fit the antisocial stereotype.  Sadly they come out of the woodwork at conventions and stare, point, and try to hover-hand in posed-pictures with others.  Sad. As for conventions I suspect you'd do OK if you just google'd "Star Trek $city-name".  It's a popular franchise and there are groups, and similar all over the place.  Even here in Nordic-land.
