Go to your local hall and sign the books as a groundman(the pay is similar to what a first year apprentice makes and the experience of being on a crew helps too). Also get a CDL probably class A with air brakes and a trailer endorsement. Til then, bide your time learning how to tie knots and read the posts in the "Linework" section of this forum because these guys are all pretty smart and you can learn a lot from reading.
