I love the free activities organized by different Meetup.com hiking groups. There's no pressure to join anything, no political agenda, and no requirement to attend any get together. Once you sign up (free), you get email invitations to all the activities you're interested in. You can choose to RSVP Yes or No, or sometimes Maybe, anonymously.
Hikes and other activities are well-described and you can review events online after each outing. Meetup.com also offers hundreds of other interest groups, so if you're looking to get out on the town or the water, there's a group for you too. — August 20, 2009 10:34 a.m.
