Trails started in Melbourne by Lachlan Conn and Michael Fikaris in 2004.
People get together somewhere and work on small exercises. Drawing. Writing. Talking. Thinking.
Sometimes there is a special guest in town, sometimes there is a coffee machine or a paper sponsor. 
The collected pages are then scanned and printed up as a small collection.
Next Trails get together you can pick up a copy of the last one.
They have happened up in many studios and there have been many collections printed.
Not very regular since 2012 but always fun the 'Trails night' has an irregular blog here 
And some leftover copies can sometimes be found in the storeroom.
