Dr. Gary Introduces the Primary, Secondary, and Tertiary Sectors of Economic Activity

Dr. Gary introduces the concept of sectors of economic activity as part of the discussion for Lesson 6 (Economic Activities) in GEO 151v, Human Geography. Primary, secondary, and tertiary sectors are covered all while Dr. Gary jams on a gorgeous guitar (1956 Gisbon Les Paul Custom) at Elderly Instruments (elderly.com) in Old Town Lansing, Michigan.

Please note that we did not intentionally film Dr. Gary with his head topped off... though he notes that by doing so, we cut down on the glare. (haha)
