I sat for an hour and watched a guy do that on the big cable towers behind my sister's house. Fascinating. Whatever they pay that guy and the helicopter pilot, they deserve it.
It's like the guy who drives the dynamite truck for a mining company. He was being interviewed by a reporter for a story. The reporter asks him how he came to have such a dangerous job. The guy replies that he had been a school bus driver for 20 years but he lost his nerve.
