A downtown St. Louis park is a micro tent city occupied by protesters as part of a nationwide grassroots demonstration speaking out about corporate greed and other issues. The demonstrations are often known as "Occupy [enter location where gathering takes place here]." In this case, it's OccupySTL.
About three dozen protesters were in Kiener Plaza on Monday a few blocks from the Gateway Arch. About a half-dozen tents gave some of them shelter.
