Yup, I can write an extension method for it and I have the IEnmerator implmented:

IEnumerator<Location> IEnumerable<Location>.GetEnumerator() //nothing

        {

            return _locs.GetEnumerator();

        }

        System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() //nothing

        {

            return _locs.GetEnumerator();

        }

In "string printitout = string.Join(",", test);" the list is in there, I just can't figure out how to make it output as a string value.
