I did this for a good while, went through an apprenticeship but doing something else currently. It is about the only way to make decent money without a degree in a rural area. If you ride/race moto you'll be fine with the dangers, I actually enjoyed the climbing. As an apprentice you will do all the hard labor and you need some thick skin. There is so much to learn and memorize, takes dedication. Once you are journeyed, you can literally find a job anywhere. Your friend was right it's more of a lifestyle than just a job. When you work for a small utility they could call you to work 24/7, 365 in the worst possible weather. The older lineman I worked with had nice houses, toys, financially taken care of families but gave off the vibe they wish they would have studied something and gone a different route, there is not many positions to advance to besides Lead or Superintendent. It really is a decent job, I may have to go back to some day. It has some great benefits.
