Apparently Northwesterners are not afraid of heights and have a yen for adventure. We draw that conclusion because the industry of zip line tours and aerial adventure parks is booming in the Northwest right now. Within the past couple years, fully a dozen commercial zip line attractions have opened in Oregon, Washington and Idaho... not counting at least twelve more in British Columbia and Alaska. The revenue potential has some municipal parks departments looking to add spendy zip line attractions in public parks. Correspondent Tom Banse reports from Eatonville, Washington.
