Go to the E end of Mission instead!
Park by the school below the church and walk out on a line between the cross on top of Lebret, and the microwave tower on the S side. Out in the middle there
and a little SW. Jeez it's hard to do this with a straight face! Hold on, I'll try to find a satelite pic didn't work...go to terra-server.com, click intenational...no, forget it, you'll do all right.
Terra-server, cities/international/fort qu appelle.click right direction..this is a pretty good site for satellite pics! I think you can drive on at Collingwood, but the boat launch at Rowan's had a ton of snow on it so I wouldn't plan on driving on there.
have a Merry Christmas, Buzzbomb
