Yes, but it doesn't have to be a single purpose beyond perhaps having fun in a group. One of the more popular groups in the Baltimore / Washington / Annapolis is the Second Half Fun Rally group -- a group for people in the second half of their lives who just want to have fun. The activities can be anything from an easy hike to a get together for a concert, happy hour, museum visit, community festival, or most anything else that nearly anyone can take part in and enjoy. Beyond the range of activities, the organizer is able to arrange and attend several meetups each month which seems to help in a "maintain the momentum" sort of way.
