A group of protesters who gathered on the Aamjiwnaang First Nation near Sarnia say they oppose plans to reverse the flow of oil in an Enbridge pipeline.
   The Line 9 pipeline goes through the Sarnia area and reversing the flow would allow Alberta crude to move to Montreal.
   Spokeswoman for the protest Vanessa Gray, 21, says she's worried about an oil spill similar to one that happened three years ago in Michigan.
   She says about 20 people gathered Saturday afternoon for a peaceful protest.
   Line 9 runs in two sections from Sarnia, Ont., to North Westover, near Hamilton, and then from there to Montreal.
   A protest last month in North Westover led to the arrest of 18 protesters who refused to leave a pumping station.
