One group went to Sequoia Adventure Course, and went as high as 80ft in the air, while balancing on logs, climbing cargo nets, balancing on cables, trying to sabotage others into falling, flying on ziplines, partnering up to make the exercises even more challenging, and screaming during the 15ft free fall. Very fun and as difficult as one wants it to be, so everyone finds challenges.
The other group did all ziplines.
