About 400 young men and women arrived at Penn College on Sunday for Pennsylvania Free Enterprise Week, a one-of-a-kind summer program that offers rising high school juniors and seniors a uniquely challenging opportunity to see what it is like to run their own businesses. Inaugurating the college’s eighth summer as a PFEW co-host (with Lycoming College), the teenagers were acclimated to a full college experience: moving into on-campus housing, eating meals in the Keystone Dining Room and attending programs in the Klump Academic Center. In addition to forming simulated companies and making imaginary business decisions all week long, the students will learn more about Penn College through activities that will include a campuswide quiz Wednesday.
