An open bluegrass and old time country jam is held at La Sierra Mexican Grill in Dundee Oregon on the 1st and 3rd Tuesdays of each month.  This jam is dedicated to the memory of Jon Cooper who kicked it off many years ago, but passed on himself in 2015.  The pickers average intermediate in skill level, but the jam is open and encouraging to all skill levels.
