These Mayan performers climb to the top of the pole, wrap ropes around and around the pole, tie the other end of the ropes to themselves, then slowly descend to the plaza below. One member of the group remains seated at the top playing music while the others descend.
Note that we arrived the day before performances began. This pole, which must be at least 60 feet tall, was installed on the plaza the day before. They chipped a hole in the existing concrete plaza, inserted the pole, and mixed some cement to patch it up. Then they entrusted their lives to it!
