While surfing the web the other day, I came across a Meet Up group called the Hiking Buddies. http://www.meetup.com/Hiking-Buddies/
Organized hikes and walks throughout Durham Region on Wednesday Nights and Weekends; now that's sound like my cup of tea. Night Hiking under Full Moon, Snowshoeing and Owl Prowl are upcoming events. I'm gonna join this group and keep you posted!
