    That's what typically happens. 

    Drilling a weep hole in the leg doesn't do much good since the water 
trapped in the leg below the weep hole and in the concrete can't escape 
(unless you've put gravel in the bottom of the hole which everyone has 
mentioned). When a freeze comes along, the water trapped in the leg will 
freeze, expand and split the leg above the base. So a weep hole really isn't 
going to do you much good.
