SLAGA is comprised of geocachers who live in an area around St. Louis, Missouri. Many of our members live in the city limits, or in counties in Illinois and Missouri that surround the city. SLAGA Territory is an arbitrary boundary that encapsulate much of the area where our members live and spend their time hunting for caches. It is an imaginary region, eminating from an area southwest of St. Louis for 100 miles in all direction. We are just one of many geocaching groups in the midwestern United States.
