This made me think about the movie Over the Hedge. The raccoon character RJ says to his friends, who inquire about a Hummer SUV, in the movie that "Humans are slowly losing to ability to walk".It seems like it is like this basically everywhere. Not many people seem to be interested in anything that requires physical movements. People are getting lazy.
There are probably groups in my area, but I have never really looked for anything. While I like hiking, and walking trails, I really am not wanting to go at anyone's pace but my own.
