“Clear!” shouts guide Cedric Knudsen from across a grove of Cypress trees. Five other adventurers in my group already have made that first leap onto the zip line. Now, it’s my turn. I sit back in the harness and step off the platform, forcing myself not to look down at the 30-foot chasm between my feet and the ground. There’s no time to dwell on the precariousness of my lofty perch as I swiftly whiz through the air. I let out a few laughs while enjoying the view and then, all too quickly, I’m slowing down for landing.
