it is right in truro paul, right behind the mall where zellers used to be.  sears is the anchor on the left side of the mall.

from the 102

take the robie street exit to the right, that's where all the construction is happening on the new roundabout.  continue on robie street through first set of lights (strip mall with Staples on the right) and on to the next set of lights where you turn left.  you should see Sears on the end of the mall as you turn.

go round back of the mall and continue about a kilometer or so until you ALMOST come to the four-way stop.  the road to the field is hard to see but it is on the left about a hundred yards before the four way stop.  you should be able to see cars and flyers out in the field to the left as you come down the back side of the mall.
