Maybe I'm doing something wrong or I'm not in the right places but I attend, lead projects and socialize at my college's physics, robotics, and engineering clubs, but the likeminded people I do find either aren't very social or aren't compatible with eachother. Thats not to say I dont get a small group going every once and awhile its just the overall pattern is people graduate, drift off, and any new members.. to put it kindly, dont exercise the same level of critical thinking.
Maybe I'm just in the wrong places, college is a joke afterall, but I'm just curious if this is the kinda thing you ment by locally or not.
