Since we don't have any easy opt-in/out message list capability here, this meetup entry is an attempt to make an easier way for people to get together to shoot on short notice.
If you're heading out to shoot (and would like to invite others), post the details to the discussion section here. If you want to be notified when someone is heading out to shoot, just RSVP that you're going to this event and you should get an email when someone posts.
