Hiking groups used to plentiful in the mid-Atlantic region on meeetup. Though it's been pretty dead in that regard for a year or two. Also similarly with tech meetups. Like the New York Tech meetup was or used to be a huge event that helped launch a good amount of well known startups. Where did that community go to (had the pleasure demoing there once with other fellow unknown startups at the time like Tumblr & Vimeo)?
