OMG, now that brings back memories... My first mega corp job, I had to learn to climb poles too and also learn to properly use ~20 extension ladders... I still remember the "fireman rule" for spacing a long extension ladder. The poles we were climbing were only about 20' high but it sure seemed higher... There were about 15 to 20 poles in the "pole yard" and they were spaced about 15' apart. The students each climbed up their pole and belted off... Then the instructor would throw up a basketball to one of the climbers.. Then we had to pass the ball around to others at the top of their poles.... If you dropped the ball, you had to climb down to get it, throw it back up and then climb the pole again. Taught me to trust the gaffes and belts. Also had to drill holes, hang wire, etc. It also taught me the value of "thinking" about the job I was going to do and bring everything I needed up the pole the first time.
