The Farmer’s Market in Billings is back.  The bell will ring Saturday morning to kick off the 33rd annual Yellowstone Valley Farmers Market in downtown Billings.  Sales of fruits and vegetables and a host of other items, in addition to ready-to-eat offerings, begins precisely at 8 a.m.  The market opens on Third Avenue North, from North Broadway to North 29th Street, and along those two blocks for the popular, 13-week market.
