It really is all the random days that become the best memories. I remember sitting at home one Saturday and thinking, "We should go find a free zoo." I looked up one in our area and loaded my wife and sons into the car. When we got there, we saw they had a small train ride that went around the perimeter of the whole park. My oldest (I think he was 8 or 9 at the time) enjoyed it so much that he cried and told us that was the best day ever. All because I randomly decided to take them out to do something.
