My father-in-law is very involved with the local Rotary where we live. I've attended a few meetings and play in the annual golf tournament. I've recently thought that they need to adapt in order to attract younger people (I'm 40 and I feel young around them) or a new organization needs to start (see my other comment in this thread).

What I like about the group is they build real, face-to-face relationships with one another. Plus, they do a lot to raise money for the community (helping local HS groups, families in need, etc.).
