We have one more section of Progress & Poverty, Thursdays beginning November 17 (except Thanksgiving). See the schedule here and course description here. More sections will be offered in 2012, of course.
Another option is on-line instruction thru the Henry George Institute. HGI assigns an individual instructor for each student, and some of these instructors are the same folks who teach at various Henry George Schools. Individual tutorials in Chicago can also be arranged.
If geography is your constraint– you can’t get to downtown Chicago for classes– consider sponsoring a Progress & Poverty course in your neighborhood. You secure a location and help promote the class. We provide an instructor and materials, and can also furnish limited funds to defray site costs and local advertising. Contact us if you’d like to explore this option.
