Meetup.com - I was sure it was all pervo serial killers. Clearly a set up for certain abduction - or at the very least a long tedious conversation with the loneliest people on earth.
Instead, it was a beautiful, cool & bug-free walk along a paved path thru the woods with a nice gang and even a few dogs. Really, don't know how it could have been better. Might even do it again one day.
