Cream together 2 cups margarine,2 cups brown sugar, 2 cups plain sugar and 2 teaspoons vanilla. After completing that, add the beaten eggs to the mixture. In a separate bowl mix together 3 cups plain flour, 2 teaspoons salt, and 2 teaspoons soda. Add dry ingredents to the creamed mixture and mix well. Add 6 cups of quick oats. (I like to refridgerate my batter over night). Drop on a cookie sheet covered with parchment paper or a silicone baking mat. Bake for 15 minutes at 350 degrees. Let cookies cool for a few minutes before removing to a cooling rack.
